import javax.swing.JFrame; public class Swingtest { static final int WIDTH = 500; static final int HEIGHT = 500; public static void main(String[] args){ JFrame jf = new JFrame("hello,Swinghahahahahah !"); jf.setSize(WIDTH,HEIGHT); jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); jf.setVisible(true); } }
运行后出现的是一个提示框,提示框的边框上写着
"hello,Swinghahahahahah !"
