/*
|
||||||
|
jdk8接口中添加了静态方法
|
||||||
|
静态方法:封装接口相关的通用的功能,提供辅助工具的方法。
|
||||||
|
|
||||||
|
接口的静态方法定义:
|
||||||
|
public static void method(){
|
||||||
|
|
||||||
|
};
|
||||||
|
|
||||||
|
-----------------------
|
||||||
|
接口中的静态方法的使用:
|
||||||
|
只能通过接口名.静态方法(参数列表)直接调用
|
||||||
|

public class Demo03 {
|
||||||
|
public static void main(String[] args) {
|
||||||
|
MyInterfaceImpl myInterface = new MyInterfaceImpl();
|
||||||
|
//myInterface.method();//错误,接口的静态方法不能通过实现类对象来调用,由于接口与类是多实现的
|
||||||
|
MyInterface.method();
|
||||||
|
}
|

}
