问题 I have a Ingredient class public class Ingredient { String NameP; List ListS; String Desc; List ListT; ... multiple instances of this class are stored in a Objects list. I have also a javax.swing.JList ListIng; With it's model set to ListIngModel = new DefaultListModel(); The idea is to use the Jlist to display the field "NameP" of all objects, select one of them to be further inspected and then grab the selected object: Ingredient Selected = ListIngModel.get(ListIng.getSelectedIndex()) I can

问题 I'm trying to create a simple program to manage Employees. When trying to add a new employee I can't seem to get the employee to be displayed on the Jlist.

问题 If I have the following scenario DefaultListModel model = new DefaultListModel(); model.addElement(file1.getName); model.addElement(file2.getName); ... //Add to list myJList.setModel(model); Now the list would obviously display the file name which is what I want. However if I were to process the files I would then need the actual path. So how would I achieve this outcome where the JList displays only the name but at the same time the model has stored the full path ? Alternately I could of

问题 I wrote a class (let's call it Model.java) that contains a Deque<T> , with methods for enqueuing and dequeuing items. Now I'm trying to tie this to a GUI JList. I'm baffled by how to somehow use my "model" data -- the Deque -- as a DefaultListModel that JList wants. I'm still struggling to really get OO concepts, as they apply to GUI programming. DefaultListModel documentation states: This class loosely implements the java.util.Vector API, in that it implements the 1.1.x version of java.util

问题 I am looking for a way to save the users input from a jlist into a txt file. It's for a homework project. I have the program set up to take user input from a textfield, then it goes into the jlist once they hit the add button. The jlist has a defaultlistmodel on it, and I'm wondering if there is a way to create a save button and allow it to save the complete jlist into a .txt file. Also, here is my code: import java.awt.BorderLayout; import java.awt.EventQueue; import javax.swing.JFrame;
