这是我写的程序，查了很长时间，有什么问题？
import java.io.*;

public class GetScreen
{
  public static void main(String[] args) throws Exception
  {
    BufferedInputStream bi = new BufferedInputStream(System.in);
    FileOutputStream fileOut = new FileOutputStream("e:\\radyjx\\doc\\java\\study\\a.txt");
    BufferedOutputStream bo = new BufferedOutputStream(fileOut);

    int flag = 0;
    while(flag != 10)
    {
      flag = bi.read();
      System.out.print((char) flag);
      bo.write(flag);
    }
  }
}

package com.dengyin.com;

import java.io.*;

public class GetScreen
{
  public static void main(String[] args) throws Exception
  {
    BufferedInputStream bi = new BufferedInputStream(System.in);
    FileOutputStream fileOut = new FileOutputStream("c:\\a.txt");
    BufferedOutputStream bo = new BufferedOutputStream(fileOut);
    try{
        char c = 0;
        while((c = (char) bi.read())!='q'){
            bo.write(c);
            bo.flush();
        }
    }finally{
        if (bi!=null) bi.close();
        if (bo!=null) bo.close();
        if (fileOut!=null) fileOut.close();
    }
    
  }
}

你這個程序應該這樣寫就沒問題了，看註釋
mport java.io.*;

public class GetScreen
{
public static void main(String[] args) throws Exception
{
BufferedInputStream bi = new BufferedInputStream(System.in);
FileOutputStream fileOut = new FileOutputStream("e:/a.txt");
BufferedOutputStream bo = new BufferedOutputStream(fileOut);

int flag = 0;
while(flag != 10)
{
flag = bi.read();
System.out.print((char) flag);
bo.write(flag);
}
bo.close();//你的數據流沒有關閉，所以數據就沒有寫進去。
}
}
