关于java 传图片

我想往java界面里插入图片，请各位大哥帮帮忙啊！谢谢
不知道有没有什么函数方法啊！

使用轻组建，javax.swing  里面的组建都可以设置图片。
import javax.swing.*;      
import java.awt.event.*;

class C extends JFrame {
    public C() {
        addMouseListener(new MouseAdapter(){
                                             public void mouseClicked(MouseEvent e) {
                                             add(new JPane(new JLabel(new ImageIcon("1.jpg"))));
                                             validate();
                                                                                      }
                                            });
        setSize(800, 600);
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }   

    public static void main(String[] args) { new C(); }
}
