关于内部类的问题

[yyouyou]

比如说有个非静态的内部类，它的实例被引用，但是它的外部类实例没有被引用，垃圾回收会不会回收外部类的对象。

package myjava;

/**
* Created by IntelliJ IDEA.
* User: Administrator
* Date: 2006-11-27
* Time: 14:49:07

*/
public class TestFinalize {
String id ;
TestFinalize(String id){
this.id =id;
ti = new TestInner(id);
System.out.println("TestFinalize constructs:"+id);
}
public void finalize(){
System.out.println("TestFinalize finalize:" + id);
}
public class TestInner{
String a="" ;
TestInner(String id){
a = id;
}
public void finalize(){
System.out.println("TestInner finalize:" + a);
}
}
public TestInner ti;
public static void main(String[] args){
TestFinalize tf1 = new TestFinalize("one");
TestFinalize tf2 = new TestFinalize("two");
TestInner ti = tf1.ti;
tf1 =null;
System.out.println("System.gc(); fisrt");
System.gc();
System.out.println(tf1);
System.out.println(tf2);
tf2 = null;
System.out.println("System.gc(); second");
System.gc();
}
}

结果:
TestFinalize constructs:one
TestFinalize constructs:two
System.gc(); fisrt
null
myjava.TestFinalize@19821f
System.gc(); second
TestInner finalize:two
TestFinalize finalize:two

好像没有被回收

恩，这个问题没有想过，关注一下。

请问内部类都什么时候用的阿?
谢谢

不想继承的时候，呵呵
