从Java从MySQL删除条目

Question

String name = tf1.getText();
b1.addActionListener( new ActionListener()
{
    public void actionPerformed( ActionEvent e )
    {
        try
        {
            Connection myConn = DriverManager.getConnection( "jdbc:mysql://localhost:3306/javaproject", "root", "noor1032" );
            PreparedStatement myStat = myConn.prepareStatement( "DELETE FROM user_info WHERE username=?" );
            myStat.setString( 1, name );
            myStat.execute();
            myConn.close();
            JOptionPane.showMessageDialog( null, "deleted" );
        }
        catch ( Exception f )
        {
            System.out.println( f );
        }
    }
} );

有人能告诉我如何通过输入人名从MySQL代码中删除MySQL中的整行吗，一行包含其他值以及ID，年龄，体重等...但是我想删除仅基于名称。
