public class AnonymousConstruction{
public static Base getBase(int i){
System.out.print("anonymouys class");//抽象类不是不能被实例化的吗？为什么能这么实例化？
return new Base(i){
@Override
public void f() {

public static void main(String [] args){

base.f();

------解决方案--------------------
- Java code
new Base(i){@Overridepublic void f() {}};
