INHERITANCE ---------------------
class Abc
{int a;
void geta()
{
 a=5;
}
int input()
{
return(a);
}
}
class Xyz extends Abc
{int z;
void get()
{
 int x;
x=8;
 z=x;}
void display()
{
System.out.println(z);
}}

class Inherit
{
public static void main(String arg[])
{
Xyz a1=new Xyz();
a1.geta();
a1.get();
int l=a1.input();
System.out.println(l);
a1.display();
}}
