一些code延伸的小程序 [英] some code which extends applet

问题描述

喜
这是我的code（抱歉把这个）我真的需要你的帮助，你会帮我，我怎么才能从这里（init方法）删除小程序，我不喜欢使用小程序还我初学我做了什么但它并不能使它确定。谢谢

解决方案

我想通过改变扩展的Applet 到延伸的JFrame

然而，的JFrame 不需要或不使用公共无效的init（）方法，让你马上要移动的code别处。
只有使之成为一个GUI程序的目标，我的建议是要么：

• 您的init（）方法重命名为 frameInit（）


• ...或只是在移动的code的init（）到构造。

Hi this is my code (sorry for putting this) really I need your help would you please help me that how can I remove applet from this(init method)I don't like use applet also I am beginner I have done something but it doesn't make it OK. thanks

  public class RedGreenGriffin extends Applet {

解决方案

I'd start by changing the extends Applet to extends JFrame

However, a JFrame doesn't need or use a public void init() method, so you'll want to move that code somewhere else. With only the goal of making this a GUI program, my suggestion is to either:

• rename your init() method to frameInit()
• ... or just move the code in init() into the constructor.
