nice info

Coding Geeks Think of self created constructor as an "overridden" constructor, which overrides the default one, so you cannot use default one by any means.

you can write default as well as static methods in your interface. Here in your implementation class you can directly use static method with the help of interface name where as you need to use super keyword for the default method. e.g. interface DefaultInterface{ default void method1() { System.out.println("I am Deafult method from DeafultInterface"); } static void method2() { System.out.println("I am static method from DeafultInterface"); } } public class DefaultInterfaceTest implements DefaultInterface { void showUses() { DefaultInterface.method2(); method1(); DefaultInterface.super.method1(); } public void method1() { System.out.println("I am Deafult method from DefaultInterfaceTest"); } public static void main(String[] args) { new DefaultInterfaceTest().showUses(); } } output: I am static method from DeafultInterface I am Deafult method from DefaultInterfaceTest I am Deafult method from DeafultInterface

Yes only the one abstract method will work.

In 1.7, it didn't matter as the implementing Class would overide the method and there was no ambiguity if the method name was same in both interfaces!

Just tried it and the result is that you have to override the method in this case. Like an abstract method. Checked exception for "unrelated defaults" occurs otherwise.

abstract class and default method are different ....u can say "why not abstract class instead of Interface" but not "why not abstract class instead of default method" because default method is a part of Interface...but not whole interface.....i hope this makes sense :)

@@srijalkc1975 can we use lambda expressions for default methods in Interface???

yes

Yes bro, but only on abstract method!
