Question

我需要一些帮助，我一直在互联网上查找代码，对于启动画面，我发现了一些完美的代码，但是有一个问题，我希望启动画面后打开我的程序它已完成加载，我该怎么做呢？这是我的启动画面的代码：

/*

package splashdemo;

import java.awt.Font;
import java.awt.Graphics2D;
import java.awt.SplashScreen;
import java.awt.geom.Rectangle2D;

使用你的启动演示主方法调用你的程序，

public static void main(String[] args)
{
   splashInit();           
   appInit();              
   if (mySplash != null)   
     mySplash.close();   

//call your program here, example HelloWorld.java

HelloWorld hello = new Helloworld();

String[] args = {};
hello.main(args);




}

加载后启动画面打开程序
