不知道为什么我写的代码图片无法显示，图片和代码（。java后缀的）放在一起的，看了半天也没有解决，
package Window;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.FlowLayout;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class tt extends JFrame{
private static final long serialVersionUID = 1L;
JPanel panel = new JPanel();
JLabel label = new JLabel("tgrf");
tt(){
this.setSize(400, 400);
this.setLayout(new FlowLayout());
this.setBackground(Color.BLACK);
this.add(panel);
panel.setPreferredSize(new Dimension(200,200));
panel.setBackground(Color.BLUE);
panel.add(label);
label.setPreferredSize(new Dimension(100,100));
label.setIcon(new ImageIcon("关闭.jpg"));
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setVisible(true);
}
public static void main(String[] args) {
new tt();
}
}
------解决方案--------------------
注意Java命名规范，类的首字母大写，试试这个代码
- Java code
