[Java Programming] Program using class and object. [Science Tutor]

2.1. Program to access variables and methods using objects.

Class Rectangle

{

                Int length, width;                                //            Declaration of variables

                Void getdata(int x, int y)  //            definition of method

                {

                                Length=x;

                                Width=y;

                }

                                Int Area( )                            //            definition of another method

                {

                                Int area=length*width;

                                Return(area);

                }

}

Class RectArea                                                     //            Class with main method

{

                Public static void main(String s[])

                {

                                Int area1, area2;

                                Rectangle obj1=new Rectangle ( );               //            creating objects

                                Rectangle obj2= new rectangle( );

                                Obj1.length=5;                                                     //            accessing variables

                                Obj1.width=5;

                                Area2=obj1.length*obj1.width;

                                Obj2.getdata(10,20);                                          //            accessing methods

                                Area2=obj.area( );

                                System.out.println(‘’Area1=”+Area1);

                                System.out.println(“Area2=”+area2);

                }

}

Output is

Area1 = 25

Area2 = 200
