package cn.usts.edu.lesson06;

import javax.swing.*;
import java.awt.*;
import java.util.Vector;

public class JComboBoxDemo02 extends JFrame {
    public JComboBoxDemo02() {
        this.setBounds(100,100,400,200);
        this.setVisible(true);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        //String[] contents = {"1","2","3"}; // 静态的写入
        Vector<Object> contents = new Vector<>();//动态写入
        contents.add("tom");
        contents.add("jack");
        contents.add("lili");
        contents.add("加载完成");


        JList<Object> list = new JList<>(contents);
        Container container = this.getContentPane();
        container.add(list);

    }

    public static void main(String[] args)  {
        new JComboBoxDemo02();
    }

}
