System.out.println("After all Chairs have been created:\n"+"Total created="+Chair.created+",total finalized="+Chair.finalized);

args[0].equals("all")){
System.out.println("gc():");
System.gc();
}

}

书上的例子 关于垃圾回收调用finalize（）函数的 结果如下
Created 47
Beginning to finalize after4791Chairs have been created
Finalizing Chair #47,Setting flag to stop Chair creation
After all Chairs have been created:
Total created=33530,total finalized=6264
bye
既然finalize（）函数是在静态变量created=4791被调用的 怎么后面出现了Finalizing Chair #47,Setting flag 也就是i==47满足条件 是怎么回事啊 。。
