static:静态方法 可以直接通过接口名调用,不能通过接口的实现对类/接口的对象调用,不能被继承与覆盖 使用案例: publicinterfaceMyInterface {staticvoidshowStaticMessage() { System.out.println("This is a static method in interface."); } }publicclassTest {publicstaticvoidmain(String[] args) { MyInterface...
In addition to declaring default methods in interfaces, Java 8 also allows us to define and implement static methods in interfaces. Since static methods don’t belong to a particular object, they’re not part of the API of the classes implementing the interface; therefore, they have to be ca...
Java Interface Static Method Java interface static method is similar to default method except that we can’t override them in the implementation classes. This feature helps us in avoiding undesired results incase of poor implementation in implementation classes. Let’s look into this with a simple...
与此同时,java8在接口中也引入了static method,它也是有方法体的,需要使用static关键字修饰。另外要特别注意的是:如果一个类中定义static方法,那么访问这个方法可以使用ClassName.staticMethodName、instance.staticMethodName两种方式来访问static方法,但是对于接口中定义的静态方法,只能通过InterfaceName.staticMethodName方式来...
1. 静态方法(static method): 可以直接通过接口名调用,无需实例化对象。 不能被覆盖(override)。 只能访问接口中的静态成员。 可以有多个实现类共享同一个静态方法。 示例代码: public interface MyInterface { static void myStaticMethod() { System.out.println("This is a static method in an interface.")...
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 ...

java 8新增了default方法,它可以在接口添加新功能特性,而且还不影响接口的实现类。下面我们通过例子来说明这一点。 复制代码 代码如下: public class MyClass implements InterfaceA { public static void main(String[] args){ } @Override public void saySomething() { ...
