那么,有人知道如何使用netbean的jTable添加行吗?我非常感谢您在这个话题上的帮助,谢谢


另外,如果删除一行与在代码中添加一行不同,那么我也希望能得到一些关于如何做到这一点的建议

您的问题之一是,您正在为您的表硬编码条目,您将需要某种形式的数据库来存储数据。您不能通过尝试添加特定编码的方法将条目添加到表中

//used to add the entry to database table
       String query = "insert into tableName (col1, col2, col3,col4) values ('data','data','data','data')";
       Class.forName("com.mysql.jdbc.Driver");
       //connection
        Connection conn = (Connection)
                //root and username and password for access to the database
        DriverManager.getConnection("jdbc:mysql://localhost:3306/NameOfDatabase","root","password");
        //create the statement that will be used
        Statement stmt=conn.createStatement();
        //executes the query statement
        stmt.executeUpdate(query);
