在Java中解决Socket中文乱码问题可以使用以下方法:

使用InputStreamReader和OutputStreamWriter来处理字符流,可以指定字符编码方式。在发送和接收数据时,可以使用指定的字符编码方式进行解码和编码。

Socket socket = new Socket("localhost", 8080);OutputStream outputStream = socket.getOutputStream();OutputStreamWriter outputStreamWriter = new OutputStreamWriter(outputStream, "UTF-8");outputStreamWriter.write("你好");outputStreamWriter.flush();InputStream inputStream = socket.getInputStream();InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "UTF-8");char[] buffer = new char[1024];int length = inputStreamReader.read(buffer);System.out.println(new String(buffer, 0, length));

在发送和接收数据时,使用getBytes()方法和指定的字符编码方式进行编码和解码。

Socket socket = new Socket("localhost", 8080);OutputStream outputStream = socket.getOutputStream();outputStream.write("你好".getBytes("UTF-8"));outputStream.flush();InputStream inputStream = socket.getInputStream();byte[] buffer = new byte[1024];int length = inputStream.read(buffer);System.out.println(new String(buffer, 0, length, "UTF-8"));

在服务器端设置字符编码方式。

ServerSocket serverSocket = new ServerSocket(8080);Socket socket = serverSocket.accept();InputStream inputStream = socket.getInputStream();InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "UTF-8");char[] buffer = new char[1024];int length = inputStreamReader.read(buffer);System.out.println(new String(buffer, 0, length));

注意:在上述代码中,要确保发送和接收数据的编码方式一致,常用的编码方式有UTF-8和GBK。
