b) Procedure: Step Details of the step no. STACK CLASS Start the program. 1 Create a class with the class name Stack to demonstrate the application of the stack. 2 Create a constructor to initialize the top value of the stack. 3 Define the method push (). 4 If the top value is equal to 9, print stack is full. Otherwise push the value in to the 5 stack. Define the method pop (). 6 If the top value is less than zero, print stack underflow. Otherwise decrement the 7 value of the stack. Create a main class with the class name teststack. 8 Create an object for the class Stack to call the methods define inside that class. 9 Call the methods push () & pop () using the objects. 10 Stop the program. 11 QUEUE CLASS Start the program. 1 Create a class with the name queue implement to demonstrate about a application of 2 queue. Declare a variable str as string and num as integer. 3 Create an object for a class queue implement. 4 Create a constructor to of the Linked List class. This class is used by importing the 5 java.util. package. This constructor is used for constructing an empty list. Get the value from the command line by using a variable str. 6 Using try and catch block to handle exception using IOException. 7 Print the elements in the queue using the statement. 8 Stop the program. 9 6

c) Program: Stack class: package SQ; import java.io.*; class Stack{ int stck[]=new int[10]; int tos; Stack(){ tos=-1;} void push(int item) { if(tos==9) System.out.println("Stack is full"); else stck[++tos]=item; } int pop(){ if(tosjavac QueueImplement.java E:\SQ>java SQ.QueueImplement Enter number of elements : 4 Enter elements : 2 4 6 8 First element :2 Last element :8 Rest elements in the list : 4 6 d) Result: Thus the Stack and queue program was compiled and executed successfuly. VIVA – QUESTIONS AND ANSWERS: 1. What is difference between Stack and Queue in java ? S.NO

Stack

Queue

1.

A Stack represents a Collection of objects that

A Queue is also a Collection of Objects

are in LIFO (Last In First Out Order).

similar to a Stack.

The Stack class provides operations that allow

Queues typically order the elements

testing for zero elements, inspection of it's top

contained within in FIFO order but this

most element, removal of it's top most element,

is not always the case.

2.

and the addition of elements.

2. What is Stack? A Stack is a first-in, last-out data structure that pops elements in the opposite order than they were pushed. By default, a Stack uses an Array for its internal storage, although this can easily be changed. 3. What is queue? A Queue is a first-in, first-out data structure that pops elements in the same order than they were pushed. By default, a Queue uses an SList for its internal storage, although this can easily be changed.

b) Procedure: Step no.

Details of the step

1

Start the program

2

Create a class with a class name Complex Number.

3

Create a constructor with the arguments a and b with integer data type.

4

Define a method getcomplexvalue( ) to get the values of a and b.

5

7

Define static method named as addition, subtraction,multiplication to perform particular function defined inside the method. Create an object for the class Complex Number and pass the values in the argument list. Call the method by using object to get the values.

8

Print the result.

9

Stop the program.

VIVA – QUESTIONS AND ANSWERS: 1. What is a ternary operator? The operator that takes three arguments is called as ternary operator. The conditional operators is the only ternary operator available in java. 2. What is the use of Integer.parseInt() method? It is used to convert the string object into integer value.
