java中JLabel怎么显示不了图片？？？

public class picture extends JFrame { JLabel label; public picture() { super("picture"); ImageIcon p=new ImageIcon("E:\\picture\\lc.pjg"); label=new JLabel("图片",p,SwingConstants.CENTER); label.setToolTipText("this is picture"); add(label); setVisible(true); label.setHorizontalAlignment(SwingConstants.LEFT); } }import javax.swing.*;
