Java Methods

TYPES OF METHODS :

1. Class Methods : which s for class e,g Box.info
2. Instance Methods :which s created wth each obj e,g b1.info , b2.info

METHOD OVERLOADING :

Same function name but different parameters (num ,type & order ) or return type. In below class shape the method area is overloaded.

class shape....

{

  display area()

            {system.out.println (''area'' = +0) ; }

  display area(int s )

            {display.out.println (s * s) ;}

   display area(int w, int h)

            {w * h ; }

  display area(int r , float deg)

            {pi * r * r ;}

}

METHOD OVERRIDING

both func must be exactly same (parameter & return type)...

class shape

{

    display area( ) {}

}

class square extends shape

{

    display area( ) {}

}

here the display area function of child class (square) has overrided the display area func of parent class(shape)..
