Implements the concept of Multiple inheritance in Java?

class a

{

public int x,y;

public void sum()

{

x=25;

y=20;

int  z=x+y;

System.out.println("sum is="+z);

}}

class b extends a

{

public int g; 

public void mul()

{

g=x*y;

System.out.println("mul is="+g);

}}

class c extends b

{

public void div()

{

int h=10;

int k=(g/h);

System.out.println("Division is="+k);

}}

class multi

{

public static void main(String args[])

{

c obj=new c();

obj.sum();

obj.mul();

obj.div();

} }
