Question

java中怎么判断输入结束，我想输入一字符串，再打印出来；

package io;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.IOException;

class io
{
public static void main(String[] args) throws IOException
{
BufferedInputStream inut=new BufferedInputStream(System.in);

byte[] buf=new byte [1024];
inut.read(buf);//输入

BufferedOutputStream out=new BufferedOutputStream(System.out);
out.write(buf);//输出

System.out.println(out.write(buf));
}
}

Answer 1

while((lenght = in.read(b))>0){
out.write(b,0,lenght);
}

Answer 2

监听一个自定义的特殊字符吧，
