怎么用java代码连接到服务器？

用Socket类去连接\x0d\x0a String ip = "192.168.0.57"\x0d\x0a int port=7000\x0d\x0a InputStream in\x0d\x0a OutputStream out\x0d\x0aSocket sock = null \x0d\x0a try {\x0d\x0a sock = new Socket(ip,port)\x0d\x0a sock.setSoTimeout(60*1000)//设置超时\x0d\x0a this.in = sock.getInputStream()\x0d\x0a this.out = sock.getOutputStream()\x0d\x0a } catch (Exception e) {\x0d\x0a throw new Exception("与终端连接失败!")\x0d\x0a }

具体实现步骤：

1、把jar文件复制进项目

2、用navicat建立数据库db_studentinfo,建立表student

3、新建项目Java，在str中建立包Second

4、建立类

Window.java

Add.java

Ask.java

Change.java

Delete.java

Look.java
