}
//响应列表框事件的方法
public void itemStateChanged(ItemEvent e) {
String name1 = list1.getSelectedItem();
String name2 = list2.getSelectedItem();
String name3 = list3.getSelectedItem();
if (name1 != null) {
text1.setText(name1);
}
if (name2 != null) {
text2.setText(name2);
}
if (name3 != null) {
text3.setText(name3);
}
}
}
}
开发完毕，最后注意就是软件不要被反编译。
除了Java可以开发qq聊天界面，c#，Android都可以写qq聊天程序
