package com.aa;

import java.awt.Component;

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

public class huatu extends JFrame {
	JPanel panel;
	JLabel label;
	ImageIcon tt;

	public huatu() {

		tt = new ImageIcon(
				"C:\Users\Administrator\workspace\Demo\bin\com\aa\3.jpg");
		label = new JLabel(tt);
		panel = new JPanel();
		panel.add(label);

		this.add(panel);
		this.setVisible(true);
		this.setSize(400, 300);

	}

	public static void main(String[] args) {
		huatu t = new huatu();
	}
}
