Java 显示图片的方法

下面是两种显示图片的简单方法：

package org.bruce.vertices.asist.experiments;

import java.awt.BorderLayout;
import java.net.URL;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class ShowImage extends JFrame {
  private static final long serialVersionUID = -6736454674070258636L;

  /**
   * @param args
   */
  public ShowImage() {
    JPanel panel = new JPanel(new BorderLayout());
    JPanel panel2 = new JPanel(new BorderLayout());
    JPanel panel3 = new JPanel(new BorderLayout());

    String urlString = "D://MyEclipse 6.0//新建文件夹//Exam//bin//images//winter.jpg";
    JLabel label = new JLabel(new ImageIcon(urlString));

    URL url = getClass().getResource("/images/orz2.jpg");
    JLabel label2 = new JLabel(new ImageIcon(url));

    URL url2 = getClass().getResource("/images/orz.jpg");
    JLabel label3 = new JLabel(new ImageIcon(url2));

    panel.add(label, BorderLayout.CENTER);
    panel2.add(label2, BorderLayout.CENTER);
    panel3.add(label3, BorderLayout.CENTER);

    this.getContentPane().setLayout(new BorderLayout());
    this.getContentPane().add(panel, BorderLayout.CENTER);
    this.getContentPane().add(panel2, BorderLayout.SOUTH);
    this.getContentPane().add(panel3, BorderLayout.EAST);

    this.setSize(400, 300);
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    this.setTitle("显示图像");
    this.setVisible(true);
  }

  /**
   * @param args
   */
  public static void main(String[] args) {
    // TODO Auto-generated method stub
    new ShowImage();
  }

}
