跪求如何解决java中由getInputStream()方法带来的Socket is closed问题？

Question

以下是报错的部分

jbt1.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e){
                num=1;
                String ss=String.valueOf(num);
                OutputStream out = null;
                try {
                    out = socket.getOutputStream();
                } catch (IOException e1) {
                    // TODO 自动生成的 catch 块
                    e1.printStackTrace();
                }
                try {
                    out.write(ss.getBytes());
                } catch (IOException e1) {
                    // TODO 自动生成的 catch 块
                    e1.printStackTrace();
                }
                try {
                    out.close();
                } catch (IOException e1) {
                    // TODO 自动生成的 catch 块
                    e1.printStackTrace();
                }
                InputStream in=null;
               try {
                    in = socket.getInputStream();//**【【【【这里被报错**
                    byte[] bs=new byte[100];//每次接受100字节
                    int len=-1;//随意赋值
                    OutputStream fileOut=new FileOutputStream("src/Client/1.jpg");

                    while((len=in.read(bs))!=-1) {
                        fileOut.write(bs,0,len);
                    }

                    //fileOut.close();
               }catch(Exception e1) {e1.printStackTrace();}

                }


        });

Answer 1

out的关闭会导致socket的关闭。

java.net.SocketOutputStream#close
