What is Multiple Inheritance in Java ?

In Multiple Inheritance one class extends more than one class or interface. Java doesn't supports multiple inheritance because multiple inheritance result in diamond problem.

Multiple inheritance means multiple classes/ interface with same methods name and this leads to ambiguity.

What is Diamond Problem ?

In below example as we have four classes i.e A ,B ,C and D ,and classes A, B and C have method with same name and class D extends B and C (In Java class can only extends one class ,if we try to extend more than one class ,then this will leads to compile time exception),now the problem comes with class D ,to override which class method i.e. B or C.

Diamond Problem

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

class A{ } class B extends A { } class C extends A{ } public class D extends B,C { //this leads to syntax error public static void main(String[] args) { } }
