下面有段代码不明白，请教一下
class Garbage
{
int index;
static int count;
Garbage()
{
count++;
System.out.println( "object "+count+ " construct ");
setID(count);
}

void setID(int id)
{
index=id;
}

protected void finalize()
{
System.out.println( "object "+index+ " is reclaimed ");
}

public static void main(String[] args)
{
new Garbage();
new Garbage();
new Garbage();
new Garbage();
System.gc();
}
}


当程序执行的时候结果如下：

object 1 construct
object 2 construct
object 3 construct
object 4 construct
object 4 is reclaimed
object 3 is reclaimed
object 2 is reclaimed
object 1 is reclaimed

但我认为结果应该是：

object 1 construct
object 2 construct
object 3 construct
object 4 construct
object 4 is reclaimed
object 4 is reclaimed
object 4 is reclaimed
object 4 is reclaimed

index的值为什么会减少呢？？？不明白，请指教....

[解决办法]
晕，index又不是static变量，四个不同的Garbage实例里面的index都不一样的啊
[解决办法]
void setID(int id)
{
index=id;
}

这句index把每个ID都记录了下来
