Constructor with Overloading in JAVA : Day 8

          a) How to Overload a Constructor? Demonstrate with example.

    

      b) How to use Object as Parameter? Give example.

Stack Programming using consturctor in JAVA : Day 7

 

 Write a program to see a practical application of the JAVA CLASS, let’s develop the Stack. A stack stores data using first-in, last-out ordering. That is, a stack is like a stack of plates on a table. The first plate put down on the table is the last plate to be used. Stacks are controlled through two operations traditionally called push and pop. Use the Class name for this program as Stack, Stack() as constructor, push() and pop() as method.

Keyword and Constructor in JAVA : Day 6

a) What is this Keyword?

b) Write any program using Parameter with Constructor.

Constructor in JAVA : Day 5

 a) What happened when a constructor initialized in an Object?

b) Write a program to find the volume of a Box. Use Constructor to initialize the dimensions of a Box. Compute and Return the result using Method.

Method with return type in JAVA : Day 4

a) How Method return a value? Write necessary Syntax.

b) Write any JAVA program that takes parameters in a Method.

Method in JAVA : Day 3

a) How to access the instance variable using Method?

b) Write a program to calculate the Volume of a Box using Method.

Object in JAVA : Day 2

a) What is Object? How to declare an Object in a JAVA program? Explain the Syntax of Object Declaration.

b) Write Syntax to assign an Object Reference Variable.

Class in JAVA : Day 1

  Explain the General Form of a Class.   --------------------------------------------------------------------------------------------------------------------------

Write a program to find the volume of a Box. Define only three instance variables: width, height and depth. Do not use Methods.

-----------------------------------------------------------------------------------------------------------------------------
package volbox;
class Bigbox
{
   double width;
   double depth;
   double height;
}
public class Volbox
{
  public static void main(String[] args)
  {
    Bigbox lbox=new Bigbox();
    lbox.width=15;
    lbox.depth=8;
    lbox.height=20;
    double vol=lbox.width * lbox.depth * lbox.height;
    System.out.println("Volume of box is:" +vol);
  }
}
