是的,Java Socket編程可以進(jìn)行數(shù)據(jù)壓縮。在Java中,你可以使用java.util.zip包中的類來實(shí)現(xiàn)數(shù)據(jù)壓縮和解壓縮。這些類提供了DeflaterInflater兩個(gè)主要的類,分別用于壓縮和解壓縮數(shù)據(jù)。

以下是一個(gè)簡(jiǎn)單的示例,展示了如何在Java Socket編程中使用Deflater進(jìn)行數(shù)據(jù)壓縮:

import java.io.*;
import java.net.*;
import java.util.zip.*;

public class CompressedSocketServer {
    public static void main(String[] args) throws IOException {
        int port = 12345;
        ServerSocket serverSocket = new ServerSocket(port);
        System.out.println("Server started on port " + port);

        while (true) {
            Socket socket = serverSocket.accept();
            System.out.println("Client connected");

            InputStream inputStream = socket.getInputStream();
            OutputStream outputStream = socket.getOutputStream();

            Deflater deflater = new Deflater();
            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

            byte[] buffer = new byte[1024];
            int length;

            while ((length = inputStream.read(buffer)) != -1) {
                deflater.setInput(buffer, 0, length);
                deflater.finish();

                byte[] compressedData = new byte[1024];
                int compressedLength = deflater.deflate(compressedData);

                byteArrayOutputStream.write(compressedData, 0, compressedLength);
            }

            deflater.end();

            outputStream.write(byteArrayOutputStream.toByteArray());
            outputStream.flush();

            socket.close();
            System.out.println("Client disconnected");
        }
    }
}

在這個(gè)示例中,服務(wù)器接收客戶端發(fā)送的數(shù)據(jù),使用Deflater對(duì)數(shù)據(jù)進(jìn)行壓縮,然后將壓縮后的數(shù)據(jù)發(fā)送回客戶端??蛻舳耸盏綌?shù)據(jù)后,可以使用相應(yīng)的解壓縮方法(如Inflater)對(duì)數(shù)據(jù)進(jìn)行解壓縮。

請(qǐng)注意,這個(gè)示例僅用于演示目的,實(shí)際應(yīng)用中可能需要處理更多的細(xì)節(jié),例如錯(cuò)誤處理、多線程等。
