Default and static methods in an interface

Up until Java 1.7, it was not possible to define a method inside an interface. Now, 1.8 introduces the default methods through which we can provide implementation for a method inside the interface. Let's see an example of this here:

interface Phone{
 void dial();
 default void text() { 
 System.out.println("Texting a message");
 }
}

Static methods in Java are those methods that can be invoked without creating an object of a particular class, provided that the static method is in that particular class. In Java 8, static methods can be defined inside an interface, as shown here:

interface Phone {
    inx x;
    void changeRingtone();
    static void text() {
        System.out.println("Texting");
    }
}
public class PhoneDemo {
    public static void main(String[] args) {
        Phone.text();
    }
}

You can invoke the text() method directly using the name of the interface.
