    String user="test"; 
    String password="test"; 
    Connection conn= DriverManager.getConnection(url,user,password); 

　 2.DB2数据库 

    Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance(); 
    String url="jdbc:db2://localhost:5000/sample"; //sample为你的数据库名 
    String user="admin"; 
    String password=""; 
    Connection conn= DriverManager.getConnection(url,user,password);

    Properties sysProps = System.getProperties(); 
    SysProps.put("user","userid"); 
    SysProps.put("password","user_password"); 
    Connection conn= DriverManager.getConnection(url, SysProps); 

　 5.Informix数据库 

    Class.forName("com.informix.jdbc.IfxDriver").newInstance();
