Can a method be declared Default & Static together in an Interface? What is the benefit of using static methods in interfaces? Can interfaces have both static and default methods? Is it mandatory to provide an implementation for static methods in an implementing class?
We can use Interface’s static methods toencapsulate behaviours we don’t want sub-interfaces or sub-classes to override or inherit. Also,we can use the static methods to build reusable utilitiesthat are not bound to any specific implementing classes or types. Rules of Static Methods in a Jav...
static void staticMethod() { System.out.println("This is a static method in the interface."); } } 示例 在这个示例中,我们定义了一个名为 MyInterface 的接口,它包含一个常规方法 doSomething() 和一个静态方法 staticMethod()。 package com.hxstrive.jdk8.interfaces; public class InterfaceDemo3 { ...
Nonetheless, static and default methods in interfaces deserve a deeper look on their own. In this tutorial, we’ll learn how to use static and default methods in interfaces, and discuss some situations where they can be useful. Further reading: Private Methods in Java Interfaces Learn how t...

Since JDK 8 it is possible to have static methods in interfaces. However, there is no way to execute them from debugger. Static method in classes can be run by com.sun.jdi.ClassType.invokeMethod(). But there is missing corresponding com.sun.jdi.InterfaceType.invokeMethod(). ...

This feature enables an interface to define static members. This enables interfaces to define operators that must be provided by implementing types.
