JAVA METHODS

     The general form of a method is as follows:

type  methodname(parameter-list) {

                   //body of the method.

          }

o   type specifies the type of data returned by method. Ifmethod does not return any value then type should be void.

o   The methodname specifies the name of the method.

o   The parameter-list is a sequence of type and identifier pairs separated by commas.

Ex:class Myclass {

          int  a;

          int b;

          void  Getdata(int x,int y) { //Method with parameters.

                   a=x;

                   b=y;

          }

void Display() { //Method with no parameters.

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

          }

int sum() { //Method that return some value.

                   return(a+b);

          }

    }

class Mymain {

          public static void main(String args[]) {

                   Myclass c1=newMyclass();

                   c1.Getdata(10,20);//Accessing method

Myclass c2=new Myclass();

                   c2.a=30;// Accessing Member variables

                   c2.b=40;

                   c1.Display();

                   int sum=c2.sum();

                   System.out. print("\n Sum of Second object is:"+sum);

          }

}

Output: A= 10  B= 20

               Sum of Second object is: 70
