【请教】关于流的关闭

Question

我打算将文件压缩成jar的包，当我试图关闭流时，会出错。如果不关闭，让gc来处理则没有问题。
代码如下： try {
JarOutputStream o = new JarOutputStream(
new FileOutputStream("c:/haha.jar"));
String[] s = MyFrame.this.ta.getText().split("\\s");

for (String ss: s){
System.out.println(ss);

JarEntry en = new JarEntry(ss);
o.putNextEntry(en);
BufferedInputStream bin = new BufferedInputStream(new FileInputStream(ss));
BufferedOutputStream bo = new BufferedOutputStream(o);
File f = new File(ss);
byte [] b = new byte[(int) f.length()];
bin.read(b);
bo.write(b);
bin.close();  // 这两个close出错！
bo.close();   // 这两个close出错！
o.closeEntry();
}

o.close();
} catch (IOException e1) {...}
错误提示：java.io.IOException: Stream closed

不好意思，帖子里的代码太乱了，我重新贴一下：try {  JarOutputStream o = new JarOutputStream(new FileOutputStream("c:/haha.jar"));
  String[] s = MyFrame.this.ta.getText().split("\\s");
  for (String ss: s){
    System.out.println(ss);
    JarEntry en = new JarEntry(ss);
    o.putNextEntry(en);
    BufferedInputStream bin = new BufferedInputStream(new FileInputStream(ss));
    BufferedOutputStream bo = new BufferedOutputStream(o);
    File f = new File(ss);
    byte [] b = new byte[(int) f.length()];
    bin.read(b);
    bo.write(b);
    bin.close();  // 这两个close出错！
    bo.close();   // 这两个close出错！
    o.closeEntry();
}

o.close();
} catch (IOException e1) {...}
