Write a program in Java to demonstrate single inheritance, multilevel inheritance and hierarchical inheritance.
AIM: Write a program in
Java to demonstrate single inheritance, multilevel inheritance, and hierarchical
inheritance.
CODE:
class pin{
int
gpin=380009;
int
hpin=382350;
char
o;
void
pin(char o){
this.o=o;
if(o=='H'){
System.out.println(hpin);
}
else{
System.out.println(gpin);
}
}
}
//simple inheritance
class India extends pin{
char
o;
void
indiaadd(char o){
this.o=o;
System.out.print(",India");
super.pin(o);
}
}
//multilevel
class Guj extends India{
char
o;
void
gujadd(char o){
this.o=o;
System.out.print(",Gujarat");
super.indiaadd(o);
}
}
class ahm extends Guj{
char
o;
void
ahmadd(char o){
this.o=o;
System.out.print(",Ahmedabad");
super.gujadd(o);
}
}
//hierarchical inheritance
class home extends ahm{
void
homeadd(){
System.out.print("C-203,Surabhi
Residency,Nikol");
super.ahmadd('H');
}
}
//hierarchical inheritance
class gpg extends ahm{
void
gpgadd(){
System.out.print("GPG,
opp. PRL ");
super.ahmadd('G');
}
}
public class p19{
public
static void main(String args[]){
System.out.println("\n\nCollege
Address");
