JAVA CLASSES

\   Classes provide a convenient method for packing together a group of logically related data items and functions that work on them.

    In Java, the data items are called fields and functions are called methods.

    A class is declared by using class keyword:

class classname {

          type  instance-variable1;

          type  instance-variable2;

          //….

          type  instance-variableN;

          type  methodname1(parameter-list) {

                   //body of the method.

          }

type  methodname2(parameter-list) {

                   //body of the method.

          }

          //….

type  methodnameN(parameter-list) {

                   //body of the method.

          }

}

Ex:

class Myclass {

          int  a;

          int b;

          void  Getdata(int x,int y) {

                   a=x;

                   b=y;

          }

void Display() {

                   System.out.println(“A= “ +a+ “ B= “+b);

          }

    }
