import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JList;
import javax.swing.JSplitPane;
 
public class fenye1 extends JFrame{
 
    JLabel jl;
    JList js;
    JSplitPane jp;
 
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        fenye1 f1=new fenye1();
    }

        {
        String [] a={"软件开发","软件测试","数据挖掘"};
        jl=new JLabel(new ImageIcon("image/23.jpg"));
        jl.setBackground(Color.pink);
        jl.setOpaque(true);
        js=new JList(a);
