java源程序如下：
//java
import java.sql.*;
public class dbexam3
{
public static void main(String[] args)
{
  Connection connection;
  Statement sqlstate;
  ResultSet result;
  try
  {
  Class.forName("com.mysql.jdbc.Driver");
  connection=DriverManager.getConnection("jdbc:mysql://localhost:3306/stud","root","");
  sqlstate=connection.createStatement();
  result=sqlstate.executeQuery("select * from stud.dep");
  System.out.println("*---------------*");
  while(result.next())
  System.out.println("depid:"+result.getString("depid")+"\n"+"depname:"
                                          +result.getString("depname"));
      connection.close();
  }
  catch(Exception e)
  {
  System.out.print("error:"+e+"\n");
  }


mysql装在本机上，数据库stud中有一张表dep（depid varchar,depname varchar）
输出结果汉字成乱码：

安装mysql的时候用utf-8做为默认编码
或在程序中插入数据时对数据编码
