15.5 匿名内部类

泛型可以用于匿名内部类

package com.cnsuning.src;public class Main {public static void main(String[] args) {Generator<Robot> g = Robot.generator;for(int i=0;i<5;i++){System.out.println(g.next());}}}interface Generator<T>{public T next();}class Robot{private static int count=0;private int id=count++;public String toString(){return "Robot "+id;}public static Generator<Robot> generator = new Generator<Robot>(){@Overridepublic Robot next() {// TODO Auto-generated method stubreturn new Robot();}};private Robot(){}}

运行结果:

Robot 0
Robot 1
Robot 2
Robot 3
Robot 4
