Multilevel inheritance is a java feature where the properties of a class are inherited by a class which extends one or more classes which extend its features...
Example:
public class A {
public String getName(){
return "Rocky";
}
}
public class B extends A {
public int getAge() {
return 24;
}
}
public class C extends B {
public String getAddress(){
return "North Carolina, USA";
}
}
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:
Rocky
24
North Carolina, USA
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.

What does java not support?
Java does not support multiple inheritance.......
How can you write multiple inheritance program in java?
Java does not support direct multiple inheritance. You can implement partial multiple inheritance using interfaces. ex: public class ExMultInherit implements interface1, interface2, interface 3 { ... .... ...... }
Give the structure of multiple inheritance?
Java does not support multiple inheritance. It is done with the help of interfaces in java. a class can implement n number of interfaces, thus showing multiple inheritance. but a class cannot extend multiple classes in java.

How ploymorphism and inheritance is different from that in Java and c plus plus?
C++ allows multiple inheritance while Java does not. In my opinion, multiple inheritance is not useful because it can get very confusing very quick. For polymorphism, C++ does early binding by default, while Java does late binding by default. Late binding is more useful than early binding.

What is public inheritance in java?
Inheritance is a Java feature by which we can reuse code and programming logic from one class in another class. We implement Inheritance using the extends keyword.Ex: public class Ferrari extends Car {…}Here the Ferrari Class will extend features from the Car Class.This is Inheritance. The different types of Inheritance are:Single InheritanceMulti-Level InheritanceMultiple Inheritance (Java supports only Partial Multiple Inheritance) andHybrid Inheritance
