Thread one = new Thread(this);//新建一个线程

one.start();//启动这个线程，到上面的run方法

one = null;//把这个线程置为空，让它执行完以后就释放

}

如果你想一下自己写要怎样写这个程序，就很容易理解这个程序了。

一直从下向上画圆，然后把下面的圆擦掉，就能得到一个向上升的烟花效果，

爆炸效果就是先画小圆再画大圆，然后擦掉小圆，再擦掉大圆。

常用的编程语言。

编程语言一：C语言

C语言是世界上最流行、使用最广泛的高级程序设计语言之一。在操作系统和系统使用程序以及需要对硬件进行操作的场合，用C语言明显优于其它高级语言，许多大型应用软件都是用C语言编写的。

编程语言二:java

Java是一种可以撰写跨平台应用软件的面向对象的程序设计语言，是由Sun Microsystems公司于1995年5月推出的Java程序设计语言和Java平台（即JavaSE, JavaEE, JavaME）的总称。

编程语言三:c++

C++这个词在中国大陆的程序员圈子中通常被读做“C加加”，而西方的程序员通常读做“C plus plus" , "CPP”。 它是一种使用非常广泛的计算机编程语言。C++是一种静态数据类型检查的、支持多重编程范式的通用程序设计语言。
