[Java Programming] Programs using Constructors. [Science Tutor]

3.1: Program on Default Constructor.

Class Default

{

                int length,width;

                Default()

                {

                                Length=5;

                                Width=5;

                }

                int Area()

                {

                                Return(length*width);

                }

}

Class DefaultMain

{

                Public static void main(String s[])

                {

                                Default obj=new Default();

                                Int result=obj.Area();

                                System.out.println(“Area=”+result);

                }

}

Output

Area=25

3.2. Program on Parameterized Constructor.

Class Parameter

{

                Int length, width;

                Parameter(int x, int y)

                {

                                Length=x;

                                Width=y;

                }

                Int Area()

                {

                                Return(length*width);

                }

}

Class ParameterMain

{

                Public static void main(String s[])

                {

                                Parameter obj=new Parameter(10,20);

                                Int result=obj.Area();

                                System.out.println(“Area=”+result);

                }

}

Output is

Area = 200
