选择一个JList项，该项将向JTextField显示信息

Question

I have two classes. A Book class which contains the title, author, and isbn. The second class is the driver class called Library.

The GUI contains a jlist and 3 text fields. The jlist is an arraylist of items from the Book class (title, author, isbn). When one item is selected from the jlist the text fields show the: title, author, and isbn of the item.

My problem is how do I have the selected jlist item display the info in the textfields? I just need someone to point me into the right direction, I'm trying to understand this logically and then implement it into code.

*The Jlist items contain: Book 1, Book 2, Book 3 so if I select Book 1 it will display Harry Potter and the Goblet of Fire, JK Rowling, 24325543.

Answer 1

如果使用的是JList，则可以使用getSelectedIndex()获取所选项目的索引，或者使用getSelectedValue()获取对象的项目。
