将Jcombobox中的选定项目添加到Jlist [英] add selected Item from Jcombobox to Jlist

问题描述

我创建了一个Jcombobox，并从数据库中填充了它，我有一个JList，我希望我在组合框中选择的每个项目都添加到JList上.我是java的新手，我试图用此代码解决问题，但它不起作用:

i have created a Jcombobox and i have populated it from data base, i have a JList and i want every item i select in the combobox to be added on the JList. i'm new to java and i tried to solve the problem with this code but it's not working :

 private void addelementActionPerformed(java.awt.event.ActionEvent evt) {                                           

   DefaultListModel liss = new DefaultListModel();

   Object  s = empcombo_s.getSelectedItem().toString();


   for(int i =0; i<=1;i++) { 
    liss.add(i, s);
}

   stagelist.setModel(liss);
} 

推荐答案

现在此代码可以正常运行:

now this code is working properly :

  DefaultListModel liss = new DefaultListModel();
private void addelementActionPerformed(java.awt.event.ActionEvent evt) {                                           

   String  s = empcombo_s.getSelectedItem().toString();
  liss.addElement(s);
   stagelist.setModel(liss);
}
