请教各位帮我解决，
for (int i = in.read(b); i != -1;) {
sout.write(b);
//将缓冲区的输入输出到页面
in.read(b);
}
可以改成如下：
while (in.read(b)!= -1){
sout.write(b);
}
//b = new byte[color=red][0x7a120]; [/color]
b = new byte[2048];
for (int i = in.read(b); i != -1;) {
sout.write(b);
//将缓冲区的输入输出到页面
//in.read(b); 改为如下，才不会一直循环
i = in.read(b);
}
