I was learning through interfaces when I noticed that you can now define static and default methods in an interface.

public interface interfacesample2 {

    public static void method() {

        System.out.println("hello world");

    }

    public default void menthod3() {

        System.out.println("default print");

    }

}

Kindly explain the difference of the two and also if there's an example of when we would use this would be nice. A little confused on Interfaces.

Differences between static and default methods in Java 8:

1) Default methods can be overriden in implementing class, while static cannot.

2) Static method belongs only to Interface class, so you can only invoke static method on Interface class, not on class implementing this Interface, see:

public interface MyInterface {

    default void defaultMethod(){

        System.out.println("Default");

    }

    static void staticMethod(){

        System.out.println("Static");

    }

}

public class MyClass implements MyInterface {

    public static void main(String[] args) {

        MyClass.staticMethod(); //not valid - static method may be invoked on containing interface class only

        MyInterface.staticMethod(); //valid

    }

}

3) Both class and interface can have static methods with same names, and neither overrides other!

public class MyClass implements MyInterface {

    public static void main(String[] args) {

        //both are valid and have different behaviour

        MyClass.staticMethod();

        MyInterface.staticMethod();

    }

    static void staticMethod(){

        System.out.println("another static..");

    }

}
