获取 Applet 未初始化错误 [英] Getting Applet not initialized error

问题描述

我的程序一切正常吗??
当我运行它时，出现一个屏幕，但它说 Applet 未初始化

import java.applet.Applet;导入 java.awt.*;导入 javax.swing.*;公共类 JobseekerLogin 扩展框架 {公共无效创建框架(){Frame frame = new Frame("Java Swing 中的框架");frame.setSize(400, 400);frame.setVisible(true);Label lb = new Label("用户名");添加(东"，磅)；add("West",new TextArea(""));Label lb1 = new Label("密码");添加(东"，磅1)；add("West",new TextArea(""));}public static void main(String []args){JobseekerLogin obj = new JobseekerLogin();obj.CreateFrame();}}

解决方案

这个类不是作为小程序启动的，因为它不扩展 JApplet 或 Applet.

即使修复了此问题，小程序客户端中也不会出现任何内容.小程序不调用 main 方法，而是调用 init.也不要为小程序组件创建新的 Frame - 将它们添加到小程序容器本身.

不要使用旧的重量级 AWT，而是使用轻量级的 Swing.另请参阅 Java Web Start 进行部署.

is everything is right in my programme??
When i run it the a screen appears but it says that Applet is not initialized

import java.applet.Applet;
import java.awt.*;
import javax.swing.*;

public class JobseekerLogin extends Frame {

public void CreateFrame(){
Frame frame = new Frame("Frame in Java Swing");
frame.setSize(400, 400);
frame.setVisible(true);
Label lb = new Label("Username");
add("East",lb);
add("West",new TextArea(""));
Label lb1 = new Label("Password");
add("East",lb1);
add("West",new TextArea(""));
}

public static void main(String []args){
  JobseekerLogin obj = new JobseekerLogin();
  obj.CreateFrame();
}
 }

解决方案

This class is not launching as an applet as it does not extend JApplet or Applet.

Even when this is fixed, nothing will appear in the applet client. Applets do not call the main method but rather init. Also don't create a new Frame for applet components - add them to the applet container itself.

Rather than using the old heavyweight AWT, use lightweight Swing. Also look at Java Web Start for deployment.
