java8-新特性--（接口的默认方法与静态方法）

public interface Inte{

    void method();

    default  void defaultMethod(){
        System.out.println("default");
    }

    static  void staticMehod(){
        System.out.println("static");
    }
}

public static void main(String[]args){
    Inte.staticMehod();  //static

  }

private interface Defaulable {
    default String notRequired() { 
        return "Default implementation"; 
    }        
}
         
private static class DefaultableImpl implements Defaulable {
}
     
private static class OverridableImpl implements Defaulable {
    @Override
    public String notRequired() {
        return "Overridden implementation";
    }
}
