Java Swing - 如何从列表项索引获取Point值

import java.awt.BorderLayout;

import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;

public class Main {
  public static void main(String args[]) {
    String labels[] = { "A", "B", "C", "D", "E", "F", "G", "H" };
    JFrame frame = new JFrame("Selecting JList");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JList jlist = new JList(labels);
    JScrollPane scrollPane1 = new JScrollPane(jlist);
    frame.add(scrollPane1, BorderLayout.CENTER);

    System.out.println(jlist.indexToLocation(5));
    frame.setSize(350, 200);
    frame.setVisible(true);
  }
}
