Java 将字符串从一个JList移动到另一个JList

我不知道如何将字符串从一个JList传输到另一个JList。还有一个类使用main，但它只为要打开的按钮创建JFrame。我尝试了执行

rightList.setListData（leftList.getSelectedValues

，但它划掉了

getSelectedValues

package multiList;

import java.awt.*;
import java.awt.event.*;
import java.util.List;
import java.util.Vector;

import javax.swing.*;
import javax.swing.event.*;

public class Gui extends JFrame {
    private JList leftList;
    private JList rightList;
    private JButton moveButton;
    private static String[] food = {"Pizza", "Spagetiti", "Mac and Cheese", "Cheese", "MorePizza"};

    public Gui() {
        super("title");
        setLayout(new FlowLayout());

        leftList = new JList(food);
        leftList.setVisibleRowCount(3);
        leftList.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
        add(new JScrollPane(leftList));

        moveButton = new JButton("Move ---->");
        moveButton.addActionListener(
                new ActionListener() {
                    @SuppressWarnings("deprecation")
                    public void ActionPreformed(ActionEvent event) {
                        rightList.setListData(leftList.getSelectedValues());
                    }

                    @Override
                    public void actionPerformed(ActionEvent e) {
                        // TODO Auto-generated method stub
                    }
                }
        );

        add(moveButton);

        rightList = new JList();
        rightList.setVisibleRowCount(3);
        rightList.setFixedCellWidth(100);
        rightList.setFixedCellHeight(15);
        rightList.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
        add(new JScrollPane(rightList));
    }
}

这应该起作用：

DefaultListModel model = (DefaultListModel) leftList.getModel();
DefaultListModel list2Model = new DefaultListModel();
int[] selected = leftList.getSelectedIndices();
for (int i = 0; i < selected.length; i++) {
         list2Model.addElement(model.elementAt(i));
    }

rightList.setModel(list2Model);

DefaultListModel=（DefaultListModel）leftList.getModel（）；
DefaultListModel list2Model=新的DefaultListModel（）；
int[]selected=leftList.getSelectedIndices（）；
对于（int i=0；i
