What is the function used?? How do we know whether we should print the inner loop variable ro the outer loop variable in a nested loop program? If you want to print values which are same for any line and only changes when it goes to the next line, then print outer loop variable. If you want to print values which are changing within the same line, then print inner loop variable.
Hence, it is a construct that binds one or more primitive types together to be used as a single data types. It is designed by the programmer and thus, it is called user defined data types. So, we can say that if A. A class creates objects which have similar attributes.
The objects are created from the information only available in that class, hence it is liable to be called as an instance of a class. Input any number and check if it is a Palindrome Number or not. WAP to display the following pattern? Sir, is there any way to find the no. Which are the most-likely programs for boards?

Difference between a String and StringBuffer object may come. No it is not necessary to always use BufferedReader class. You can also use Scanner class for taking inputs. The example you gave might come. It is quite easy. You have to think a String to be just like an array of characters. Like you use every element in the array by writing its index, similarly, in order to access the characters of a String, you need to extract the characters through their index using charAt function.Ans: Platform is the environment in which programs execute.
Instead of interacting with the Operating System directly, Java programs runs on a virtual machine provided by Java, therefore Java is often referred to as a platform also. Ans: Bytecode is a set of pseudo mechanic language instructions that are understood by the JVM Java Virtual Machine and are independent of the underlying hardware. It hides the underlying OS from Java application. Programs written in Java are compiled into Java byte-code, which is then interpreted by a special java Interpreter for a specific platform.
Ans: The Java development kit comes with a collection of tools that are used for developing and running java programs. Ans: 1. Write Once Run Anywhere 2.
Light weight code 3. Security 4. Built in Graphics 5. Object Oriented Language 6. Support Multimedia 7. Platform Independent. Open Product. Ans: BlueJ is a Java development environment. Ans: Create: Click on new class button from BlueJ editor, then type the class name a program icon will be created.
Compile: click the compile button on the left of the window or right click on the class icon and select compile from the menu options. Execute: Right click on the class icon and select new class name option. A dialogue box appears type the name of the object.Answer any four of the following : 1. Write a Program to calculate charges for sending particles when the charges are as follows For the first 1KG Rs. Write a Java Program to accept a month using Scanner classand display the number of days present in that month Ans : import java.
Section — B Answer any Four 1. Java language provides various ways to get the data value within a program. Compare the way of using Command line argument with the way of using Input Stream Ans 1. Explain the following Math functions with their output by taking What are the differences between if …else and switch…case?
Ans : 1. If…else results in a Boolean type value whereas switch…case returns in a value of int or char datatypes 2. If…else Can perform the test for Strings also whereas switch…case cannot perform tests on String values 4. Default statement is applied in switch.

What are the differences between Entry controlled loop and exit controlled loop? Entry controlled loop is while loop whereas exit controlled loop is do…while loop 2. Do…while loop will execute at least onceeven if the condition is not satisfied whereas while loop will never execute if the condition is not satisfied 3.
While loop will check the condition first and then will execute the block whereas do…while loop will execute the block first and the check the condition. Section — C Fill in the blanks 1. Ans : i for loopii while loop or do-while loop. The paper is divided into two sections. Attempt all questions from Section-A and any four from Section-B. The intended marks for questions or parts of questions are given in brackets Follow Case-sensitivity.
Every keyword has its own task to be performed, there were many keywords in Java, which have different built-in functions to be performed, when these keywords are declared in Java programming, their built-in feature will be performed by them, so these keywords perform an important role in Java programming.

Primitive datatypes are defined implicitlythey are in-built datatypes whereas user-defined datatypes are defined by the user during the execution of the program.
Primitive datatypes are not dependent on any other datatypes whereas user-defined datatypes are directly or indirectly dependent on Primitive datatypes. The default delimiter in Jva is White space.
Examples of delimiters : Semi colon ;Coma, Question mark? It is of two types :.
A word is said to be palindrome, if it appears to be same after reversing its characters. Write a program in Java to initialize and array of 10 distinct names and initialize another array with their respective telephone numbers. Search for a name by the userin the list.
Write a program in Java to accept 10 integers in an array. Now display only those numbers having complete square root. Using scanner class accept the no.

Execution of program starts from main. The first statement of main is a for loop which sets variable i to zero. Inside the for loop is a display statement which displays i for each iteration.
So for loop is terminated. Thus values from 0 to 5 are displayed. In case of a for loop this make no difference, but in while loop test it makes a difference. Topic: for Loop In Java.
