What is the multilevel inheritance. and also give the Example
of it ?
Answer Posted / fatima deshmukh
Multilevel inheritance is a java feature where the
properties of a class are inherited by a class which extends
one class and which extend its features...
Example:
public class A {
public String getName(){
return "Fatima";
}
}
public class B extends A {
public int getAge() {
return 25;
}
}
public class C extends B {
public String getAddress(){
return "Panvel,Navi Mumbai India";
}
}
public class D extends C {
public void print {
System.out.println(getName());
System.out.println(getAge());
System.out.println(getAddress());
}
}
This method would print the following in the console:
Fatima
25
Panvel, Navi Mumbai, India
Here in class D you are calling methods that are available
inside classes A, B & C. Though D extends only class C, it
would in turn inherit the properties of the classes extended
by C and its parents.
This is multi level inheritance.

Ex:- for(char chr='A';chr<='Z'; chr++) { (int) String "count"+chr = 0; }
