tccicomputercoaching.com • Java doesn't support multiple inheritances for classes but it supports multi-level inheritance for classes and multiple inheritances in interfaces. • Let us we understand in detail why does java not support multiple inheritance?

tccicomputercoaching.com class A { void show() { } } class B { void show() { } }

tccicomputercoaching.com class C extends A,B { public static void main(String args[]) { C obj=new C(); obj.show() } }

tccicomputercoaching.com • In the above example compiler will never know which method to invoke. Because show() method is there in both classes and both classes have different implementation for show() method.

• But in interface implementation is unique if interfaces have the same method…

tccicomputercoaching.com i.e. interface I1 { show(); } interface I2 { show(); }

tccicomputercoaching.com class A implements I1,I2 { void show() { ................. .................. } public static void main(String args[]) { A obj=new A(); obj.show() } }

tccicomputercoaching.com • Here, only declaration of method given in interface but implementation given only in class. So, only method from implementing class is going to be executed. • TCCI teach all programming Language concepts in Bopal and Satellite in Ahmedabad.
