import java.awt.Image;

import javax.swing.ImageIcon;

import javax.swing.JFrame;

public class Frame extends JFrame {

public static void main(String[] args) {

new Frame().launchFrame();

}

public void launchFrame() {

setSize(300,300);

setTitle("窗口示例");

//获取图片并设为窗口图标，注意，这里的images文件夹必须和Frame.java文件在同一个包中

java.net.URL imgURL = Frame.class.getResource("/images/yourImage.png");

ImageIcon imgIcon = new ImageIcon(imgURL);

Image img = imgIcon.getImage();

this.setIconImage(img);

//将窗口显示在屏幕正中

this.setLocationRelativeTo(null);

setVisible(true);

}

}
