java的匿名类使用示例，java匿名示例,package cn.o

package cn.outofmemory.snippets.core;abstract class Abs {    public Abs(int i) {        System.out.println("Abs constructor, i = " + i);    }    public abstract void f();}public class InnerclassConst {    public static Abs getAbs(int i) {        return new Abs(i) {            {                System.out.println("Inside instance initializer");            }            @Override            public void f() {                System.out.println("In anonymous f()");            }        };    }    public static void main(String[] args) {        Abs a = getAbs(47);        a.f();    }}

输出：

Abs constructor, i = 47Inside instance initializerIn anonymous f()
