请问如何才能用java实现银行家算法，请大家帮帮我啊！

java   Bank   10   3   5   6   2   来执行  
public   class   Bank{  
public   static   void   main(String[]   args){  
//   first   decide   on   the   capital   and   the   line   credits,  
//   then  
//   read   from   the   user   client   id   and   what   he   wishes  
//   if   it   leads   to   a   safe   state   grant   it,   otherwise   not.  
Banker   b;  
int   clients,   capital;  
try   {  
//   requires   start   capital   and   number   of   clients.  
capital   =   Integer.parseInt(args[0]);  
clients   =   Integer.parseInt(args[1]);  
b=   new   Banker(capital,clients);  
//   start   the   credit   lines  
for(int   i   =0;   i<clients;i++){  
 
b.startCreditLine(Integer.parseInt(args[i+2]),i);  
b.show();  
}  
}catch   (NumberFormatException   e)   {}

有点小错。。你改改。。。

真是太谢谢你了
