I am trying to use an update method on my jtable that's connected to the database and would like to fill in the textfields on the form depending on which row the users clicks. I understand I will be needing a getValueAt() method however I am uncertain of how to fill in which row depending on which row the user clicks. I am unable to find anything on Google or anything so any information would be helpful!

推荐答案

你需要调用getValueAt（）您的表格模型可以获得您需要的值。您还需要一个监听器来监听选择。因此，一旦用户选择了一行，您就可以调用getValueAt（）来获取该行中特定数据列的值。

You will need to call getValueAt() your table's model to get the values you need. You will also need a listener on the table to listen for selections. So that once a user selects a row you call getValueAt() to get the value for the specific column of data in that row.
