Simple Socket Example

1.服務端

import ?java.io.DataOutputStream;

import ?java.io.IOException;

import ?java.net.ServerSocket;

import ?java.net.Socket;

/**

public ? class ?Server? {

???? private ?ServerSocket?server;

???? private ?DataOutputStream?output;

???? private ?Socket?socket;

???? public ?Server()? {

???????? try ? {

???????????? // ?在端口5000建立服務

????????????server? = ? new ?ServerSocket( 5000 );

????????????System.out.println( " 服務創建. " );

????????????System.out.println( " 等待客戶端連接

" );

????????????socket? = ?server.accept();

????????????System.out.println( " 客戶端已連接.\n關閉! " );

????????????output? = ? new ?DataOutputStream(socket.getOutputStream());

????????????output.writeUTF( " 歡迎你.再見! " );

????????????output.close();

????????????server.close();

????????} ? catch ?(IOException?e)? {

????????????e.printStackTrace();

????????????System.exit( 1 );

????????}

????}

???? public ? static ? void ?main(String?args[])? {

????????Server?game? = ? new ?Server();

????}

}

2.客戶端

import ?java.io.DataInputStream;

import ?java.io.IOException;

import ?java.net.InetAddress;

import ?java.net.Socket;

import ?java.net.UnknownHostException;

public ? class ?Client? {

???? private ?Socket?client;

???? private ?DataInputStream?input;

???? public ?Client(String?server,? int ?port)? {

???????? try ? {

???????????? // ?連接服務

???????????? if ?(server.equals( " localhost " ))? {

????????????????client? = ? new ?Socket(InetAddress.getLocalHost(),?port);

????????????} ? else ? {

????????????????client? = ? new ?Socket(InetAddress.getByName(server),?port);

????????????}

???????????? // ?從服務器讀取信息

????????????input? = ? new ?DataInputStream(client.getInputStream());

????????????String?info? = ?input.readUTF();

????????????System.out.println(info);

???????????? // ?關閉連接

????????????client.close();

????????} ? catch ?(UnknownHostException?e)? {

????????????e.printStackTrace();

????????} ? catch ?(IOException?e)? {

????????????e.printStackTrace();

????????}

????}

???? public ? static ? void ?main(String[]?args)? {

????????Client?client? = ? new ?Client( " localhost " ,? 5000 );

????}

}
