}小弟刚学java，不自量力的用它来编写银行家算法。星期天老师就要检查了呀，哪位大侠帮一下呀，要是程序不能通过，期末的操作系统不能考呀。

Answer 1

 to flytsu(卡休):大侠，帮我看看这到底哪里出错了，肯定给高分，拜托，拜托，星期天就要上交了。

Answer 2

Form1.java 405行出错，用微软的类，没有办法给你试

Answer 3

private boolean safetytext(int n)
{
if(n>3) return false;
....
}

Answer 4

to knight_qmh(辉):　怎么在安全算法的一开始就判断n了，那个n是代表当前向系统提出资源申请的进程号呀，n是随机的呀。哪位大侠是用VJ++6.0的呀，帮我试试呀

Answer 5

各位大侠，那个数组越界我已经调试好了，原来是在
finish[n]=true;
k=k+1;
while(k<need.length )
和
private void button1_click(Object source, Event e)
{
/**
* 判断是否成功，如成功则显示可接受的分配方案，同时改变各资源数目
* ，并且在分配时也要使的各计数器进行各自应该进行的状态，或计数或停止
* 如不行，则回复不能分配，当前进程的挂起，计数器停止计数。(要加代码)
*/
    counte();
safetytext(n);
去掉safetytext(n);
这两处改一下就不会出错了。
可是，现在如何加上计数功能了？如何是的在判断当前的进程提出申请时，它的计数器会进行计数了？
