通过文件更新JTable
[英]Update JTable through file
问题描述
Alright so I'm reading some scores off of a text file and when the user is done playing the game, it asks you if you want to save the score or not, I only have one problem with this. 
好吧，所以我从文本文件中读取了一些分数，当用户玩完游戏后，它会询问您是否要保存分数，我对此只有一个问题。 It reads and writes fine to and front from the text file, it's just that the JTable isn't updating whenever a new score is added. 它可以在文本文件中进行读写操作，只是每次添加新乐谱时JTable都不会更新。 The Object[][] is being read off a text file and I was just wondering if there was a method like "table.setData(Object[][] o);" 正在从文本文件中读取Object [] []，而我只是想知道是否存在类似“ table.setData（Object [] [] o）;”的方法。 sorta thing, any help would be greatly appreciated, thank you. 有点事情，任何帮助将不胜感激，谢谢。

Just so you can accept an answer and keep your reputation up: 这样您就可以接受答案并保持声誉：
It sounds like you need to set a DefaultTableModel . 听起来您需要设置DefaultTableModel 。
Then you can use ((DefaultTableModel) table.getModel()).setDataVector(yourData, columnHeaders); 然后可以使用((DefaultTableModel) table.getModel()).setDataVector(yourData, columnHeaders); . 。 With 'yourData' being an Object[][] , and 'columnHeaders' Object[] 其中'yourData'为Object[][]和'columnHeaders'Object Object[]
That should do exactly what you need. 那应该完全满足您的需求。
