J2ME – Interview Questions
What is J2ME
Java 2, Micro Edition is a group of specifications and technologies that pertain to Java on small devices.
The J2ME covers a wide range of devices, from pagers and mobile telephones through set-top boxes and
car navigation systems.
The J2ME world is divided into configurations and profiles, specifications that describe a Java
environment for a specific class of device.
What is a profile ?
A profile defines the type of device supported. The Mobile Information Device Profile (MIDP), for example,
defines classes for cellular phones. It adds domain-specific classes to the J2ME configuration to define
uses for similar devices.
Two profiles have been defined for J2ME and are built upon CLDC: KJava and MIDP. Both KJava and
MIDP are associated with CLDC and smaller devices.
Profiles are built on top of configurations. Because profiles are specific to the size of the device (amount
of memory) on which an application runs, certain profiles are associated with certain configurations.
A skeleton profile upon which you can create your own profile, the Foundation Profile, is available for
CDC.
What is a configuration?
In J2ME, a configuration defines the minimum Java runtime environment for a family of devices: the
combination of a Java virtual machine (either the standard J2SE virtual machine or a much more limited
version called the CLDC VM) and a core set of APIs. CDC and CLDC are configurations.
What is MIDP and CLDC.
MIDP:
The Mobile Information Device Profile (MIDP) is a specification for a J2ME profile. It is layered on top of
CLDC and adds APIs for application life cycle, user interface, networking, and persistent storage.
CLDC:
The Connected, Limited Device Configuration (CLDC) is a specification for a J2ME configuration. The
CLDC is for devices with less than 512 KB or RAM available for the Java system and an intermittent
(limited) network connection. It specifies a stripped-down Java virtual machine1 called the KVM as well as
several APIs for fundamental application services. Three packages are minimalist versions of the J2SE
java.lang, java.io, and java.util packages. A fourth package, javax.microedition.io, implements the Generic
Connection Framework, a generalized API for making network connections.
What is RMS?
The Record Management System (RMS) is a simple record-oriented database that allows a MIDlet to
persistently store information and retrieve it later. Different MIDlets can also use the RMS to share data.
What is difference between j2se, j2ee and j2me?
J2SE is considered the foundation edition of the Java platform and programming environment in which all
other editions are based. J2EE is the edition of the Java 2 platform targeted at developing multi-tier
enterprise applications. J2EE consists of a set of specifications, APIs and technologies defining
enterprise application development. J2EE technology providers expose tools, frameworks and platforms
that handle a good deal of the details of enterprise application infrastructure and behavior. J2EE
implementations enjoy all of the features of the Java 2 Standard Edition (J2SE) platform with additional
frameworks and libraries added to support distributed/Web development.
What are the optional packages?
An optional package is a set of J2ME APIs providing services in a specific area, such as database access
or multimedia.
www.firstranker.com
Unlike a profile, it does not define a complete application environment, but rather is used in conjunction
with a configuration or a profile. It extends the runtime environment to support device capabilities that are
not universal enough to be defined as part of a profile or that need to be shared by different profiles.
J2ME RMI and the Mobile Media RMI are examples of optional packages.
How is data written into RMS?
Information is stored in the record store in records, and each record is an array of bytes. The methods to
save to and retrieve from a record store all represent the record as an array of bytes.
What is profiling?
The J2ME Wireless Toolkit includes a profiler, a tool that collects statistics on your application as it runs.
After the run ends, you can see which methods in your application were called, how many times they
were called, and how much time these calls took.
What is preverifier?
Preverification is a new phase in the development and deployment cycle for Java applications designed
to run on theJ2ME CLDC.
Preverification performs certain checks on the Java bytecodes ahead of runtime. If this first verification
pass is ok, the preverifier annotates the classfiles (using standard Java bytecode “attributes”, so that
these are still plain old Java bytecodes and will be executable in VMs not aware of the benefits of
preverification), and then saves the annotated class files or passes them along to the next tool in the
compile chain.
When the KVM attempts to run execute a J2ME CLDC-based application, it checks the Java class files for
these preverification annotations. Proper annotations in the class files guarantee that certain compile-time
checks were made, and so the KVM can pass through its own verfication and security checks much faster
and start executing the application more quickly.
Sun’s CLDC reference implementation SDK includes the ‘preverify’ tool. You use the tool after compiling
your code via javac (or your favorite Java compiler).
What is obfuscator
Obfuscation is a technique used to complicate code. Obfuscation makes code harder to understand when
it is decompiled, but it typically has no affect on the functionality of the code. Obfuscation programs can
be used to protect Java programs by making them harder to reverse-engineer.
What is a MIDlet
A MIDlet is an application written for MIDP. MIDlet applications are subclasses of the
javax.microedition.midlet.MIDlet class that is defined by MIDP.
What is MIDlet suite
MIDlets are packaged and distributed as MIDlet suites. A MIDlet suite can contain one or more MIDlets.
The MIDlet suite consists of two files, an application descriptor file with a .jad extension and an archive
file with a .jar file. The descriptor lists the archive file name, the names and class names for each MIDlet
in the suite, and other information. The archive file contains the MIDlet classes and resource files.
What is OTA
A major new feature of MIDP is its ability to dynamically deploy and update applications over-the-air
(OTA). OTA provisioning, previously supported only as a recommended practice, is now required as part
of the MIDP 2.0 specification. The MIDP specification defines how MIDlet suites are discovered, installed,
updated and removed on mobile information devices. MIDP also enables a service provider to identify
which MIDlet suites will work on a given device, and obtain status reports from the device following
installation, updates or removal.
The MIDP OTA provisioning model ensures a single, standard approach to MIDP application deployment
that works across the broad range of mobile devices. The MIDP OTA provisioning model has been
defined and adopted by leading device manufacturers and service providers to deliver a reliable, secure
provisioning solution.

For example: CLDC-1.0
MicroEdition-Configuration
MicroEdition-Profile
MIDlet-<n>
MIDlet-Jar-Size
MIDlet-Jar-URL
MIDlet-Name
MIDlet-Vendor
MIDlet-Version
What are high level UI and low level UI?
The Mobile Information Device Profile (MIDP) has two APIs for modifying the user interface (UI), referred
to as the highlevel and low-level APIs.
The high-level API requires you to use task-oriented abstractions to define what the user interface does.
You have no real control over what gets drawn on the screen &mdash; the java virtual machine selects
the best approach for the device. The User interface, buttons are standard and no modification can be
done.
The low-level API is aimed squarely at j2me game developers. Unlike the high-level API, the low-level API
gives you complete access to the screen and to input events. The game developer can modify the screen
or UI as required.
The game developer can either the high-level API or the low-level API, but not both.
J2me package for low level UI is javax.microedition.lcdui.*;
What is customItem?
CustomItem is customizable by subclassing to introduce new visual and interactive elements into Forms.
Subclasses are responsible for their visual appearance including sizing and rendering and choice of
colors, fonts and graphics.Subclasses are responsible for the user interaction mode by responding to
events generated by keys, pointer actions, and traversal actions.

2. FILL THE BLANKS:

Observe the dilemma of the fungus; it is a plant, but possesses no chlorophyll. While all other plants put the sun?s energy to work for them combining the nutrients of ground and air into the body structure._____1______.Chlorophyll is found in these other plants which, having received their energy free from the sun, relinquish it__2__.

In this search of energy, the fungus has become the earth?s major source of rot and decay. Wherever you see mould forming on a piece of bread, or a pile of leaves turning to compost, or a bloom down tree becoming pulp on the ground, _____3___.

With fungus action, the earth would be pooled high with_____4______.

In fact, certain plants which contain resins that are ____5_______. Specimen of the redwood tree, for instance can still be found ______6________.

You are watching a fungus acting
Resting on the forest floor centuries after having been cut down

Fungus must look elsewhere for an energy supply
Cannot produce their own store of energy
The dead plant life of past centuries
At some point in their cycle either to animal or to fungi
Fungus is vastly different from other plants
Toxic to fungi will last indefinitely.

One large passage-6marks.
I answer all question from passage in guess becos i have no time to read whole passage care fully.

QUANTITATIVE: 38 Q-40 M
ALL CAME FROM PREVIOUS YR QUESTION. U SHOULD KEEP ON UR MEMORY THE ANSWER OF EACH QUESTION .
THERE IS 3 Q FROM VENN DIAGRAM & 3 FROM PIE CHART.

1. Two pencils costs 8 cents, then 5 pencils cost how much
Sol: 2 pencils ? 8 cents => 1 pencil ? 4 cents
Therefore 5 pencils cost = 5 * 4 = 20 cents

2. A work is done by two people in 24 min. one of them can do this work a lonely in 40 min. how much time required to do the same work for the second person.
Sol: (A+B) can do the work in = 1/24 min.
A alone can do the same work in = 1/40 min.
B alone can do the same work in = (A+B)?s ? A?s = 1/24 ? 1/40 = 1/60
Therefore, b can do the same work in = 60 min

3.A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in going than coming. What is the fuel consumed in coming up?
Sol Before the trip, car is filled with = 4 ? gallon of oil
Let ?X? be the quantity of fuel consumed for the trip in one direction
The fuel consumed while going = X + ?
The fuel consumed while coming = X
Therefore, the fuel consumed for the trip = (X + ?) + X = 4 ?
? 2X + ? = 4 ? => 2X = 4 ? – ? => 2X = 4 ? => X= 2. approx
Therefore the fuel consumed while coming = 2 gallon

4. Low temperature at the night in a city is 1/3 more than 1/2 high as higher temperature in a day. Sum of the low temperature and highest temp. is 100 degrees. Then what is the low temp?
Sol: 40 deg.

a) 120 miles
b) Between 120 and 140 miles
c) 160 miles
Answer: 120 miles

6. A person was fined for exceeding the speed limit by 10mph. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35 mph, find the speed limit.
Sol: Let ?x? be the speed limit
Person ?A? was fined for exceeding the speed limit by = 10mph
Person ?B? was fined for exceeding the speed limit by = twice of ?A?
= 2*10mph=20mph given that the second person was traveling at the speed of 35mph => 35mph ? 20mph = 15mph
Therefore the speed limit is =15 mph

7.A bus started from bus stand at 8.00am, and after 30 minutes staying at destination, it returned back to the bus stand. The destination is 27 miles from the bus stand. The speed of the bus is 18mph. In return journey bus travels with 50% fast speed. At what time it returns to the bus stand?

11.) 6 persons standing in queue with different age group, after two years their average age will be 43 and seventh person joined with them. hence the current average age has become 45. find the age of seventh person?

Solution: Here the question appear as an easy one, but carried a lot of unwanted sentences and unwanted datas(i dint mention above) in exam which may confuse u on solving technique.
Let x be current average age of first 6 persons in queue and current age of seventh person be y. Then 6x will become the sum of those 6 persons age.

Now, let compute the sum of those 6 persons after two years, 6x+12 (as each and individual increase their age by 2). hence its average become (6x+12)/6 = 43 (give in question itself).

So now we can compute x from above equation. (x = 41, 6x = 246)

Let now we compute y, ((6x+y)/7) = 45, as we have value of x, compute y.

TCS Paper on 29th August 2010 @ SRMCEM, Lucknow

Question 1: There is a toy train that can make 10 musical sounds. It makes 2 musical sounds after being defective. What is the probability that same musical sound would be produced 5 times consecutively? ( 1 of _____) ?
Answer: 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/32
32 will be the answer.
(My friends got similar question with “3 times consecutively”; for that the answer would be Cool

Question 2: Peter and Paul are two friends. The sum of their ages is 35 years. Peter is twice as old as Paul was when Peter was as old as Paul is now. What is the present age of Peter?
Luckily, I had this question twice. Initially I left it because of the confusing statement but when I got the same question second time with different names of the friends (Pooja and Prasad) then I gave a little extra time and solved it.
Answer: 20 years. I simply substituted the answers in the statement to find the best fit, because the statement in the question was pretty confusing.

Question 3: The ages of two friends is in the ratio 5:6. After how many years will the ages be in the ratio 7:8?
Answer: 10 years.

Question 4: (There was a long story, I’ll cut short it). There are 5 materials to make a perfume: Lilac, Balsalmic, Lemon, Woody and Mimosaic. To make a perfume that is in demand the following conditions are to be followed: Lilac and Balsalmic go together. Woody and Mimosaic go together, Woody and Balsalmic never go together. Lemon can be added with any material. (Actually they had also mentioned how much amount of one can be added with how much quantity of the other; but that’s not needed for the question.) All of the following combinations are possible to make a perfume EXCEPT:
1) Balsalmic and Lilac
2) Woody and Lemon
3) Mimosaic and Woody
4) Mimosaic and Lilac
Answer: Mimosaic and Lilac. I have made the question here really easy to understand. But the actual question was in a twisted language and it was difficult to find the answer. It took me some time to get to the answer.
