设备管理系统java开发的源代码

很好的例子哦 大家可以借鉴一下 希望提出宝贵意见

package ku;
import java.sql.*;
public class Sql {
	 String sDBDriver=“sun.jdbc.odbc.JdbcOdbcDriver“;
	  String sConnStr=“jdbc:odbc:abc“;
		Connection connect=null;
		ResultSet rs=null;
	    public Sql（）{
	    	try{
	    		Class.forName（sDBDriver）;
	    	}catch（java.lang.ClassNotFoundException e）{
	    		System.err.println（e.getMessage（））;	
	    	}
	    }
		//执行查询类的语句。有返回
	    public ResultSet executeQuery（String sql） {
			try{
				
				connect=DriverManager.getConnection（sConnStr）;
				Statement stmt=connect.createStatement（）;
				rs=stmt.executeQuery（sql）;
			}catch（SQLException ex）{
				System.err.println（ex.getMessage（））;
			}
			return rs;
		}
	    //执行更新类的语句 无返回
	    public void executeUpdate（String sql）
	    {
	    	
	    	Statement stmt=null;
	    	rs=null;
	    	try
	    	{   connect=DriverManager.getConnection（sConnStr）;
	    		stmt=connect.createStatement（）;
	    		stmt.executeUpdate（sql）;
	    		stmt.close（）;
	    		connect.close（）;
	    	}
	    	catch（SQLException ex）
	    	{
	    		System.err.println（ex.getMessage（））;
	    	}
	    
	    	
	    }
