因此,对于作业,我必须制作一个小Java小程序并将其显示在网页上。它在NetBeans中构建得很好,但是当我尝试在网页中运行它时,它显示为灰色,如下所示:http://devii.in/7apW我硬盘上的.jar文件加载完全正常,所以我很困惑什么弄乱了它。任何帮助,将不胜感激。谢谢。

我的代码:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Apples extends JApplet {
private static void display() {
JTextField field1 = new JTextField();
JTextField field2 = new JTextField();
JTextField field3 = new JTextField();
JTextField field4 = new JTextField();
JTextField field5 = new JTextField();
JPanel panel = new JPanel(new GridLayout(0, 1));
panel.add(new JLabel("Username:"));
panel.add(field1);
panel.add(new JLabel("Password:"));
panel.add(field2);
panel.add(new JLabel("Repeat Password:"));
panel.add(field3);
panel.add(new JLabel("Email address:"));
panel.add(field4);
panel.add(new JLabel("Repeat email address:"));
panel.add(field5);
int result = JOptionPane.showConfirmDialog(null, panel, "Form",
JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
display();
}
});
}
}
答案 0 :(得分:3)
启动applet时,永远不会调用main
方法。 applet的入口点是init方法:
public void init() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
display();
}
});
}
