JCombobox接受字符数组

Question

我希望JCombobox接受一个字符数组。我似乎无法为此找到解决方法。基本上，我希望JCombobox保持价值观＆＃39; 0＆＃39; 0 - ＆＃39; 9＆＃39;，但作为字符而不是int。

char[] levels = {'0', '1', '2', '3'};
skillLevelCombo = new JComboBox<Object>(levels); //Does not work

我如何解决这个问题？我制作一个Character数组吗？如果是这样，我如何在以后获取char值？

Answer 1

这很好用：

  Character[] levels = {'0', '1', '2', '3'};
  skillLevelCombo = new JComboBox<Character>(levels);

如，

import javax.swing.JComboBox;
import javax.swing.JOptionPane;

public class ComboFun {
   private static JComboBox<Character> skillLevelCombo;

   public static void main(String[] args) {
      Character[] levels = {'0', '1', '2', '3'};
      skillLevelCombo = new JComboBox<Character>(levels); 

      JOptionPane.showMessageDialog(null, skillLevelCombo);
   }
}

请注意，整数也很有效：

  Integer[] levels = {0, 1, 2, 3};
  final JComboBox<Integer> skillLevelCombo = new JComboBox<Integer>(levels);
