In
multiple inheritance one class derived from more than one super
class.
Java
doesn't support multiple inheritance.
Why
Java not supporting multiple inheritance ?
Lets
say there is a method called print(), in the super classes A and B
class A{ void print(){ System.out.println(“I am in A”); } } class B{ void print(){ System.out.println(“I am in B”); } } class C extends A, B{ public static void main(String args[]){ print(); } }
Class
“C” is calling the method print(), then Java run time has two
options, one is in the class A and other is in class B, here is an
ambiguity. Of course there are languages like C++ provides a way to
solve this problem, but to make the Java language simple, Java
doesn't support multiple inheritance directly.
Java
supports multiple inheritance using interfaces. A Java class allowed
to implement more than one interface.
