Description: Eclipse下运行java Swarm以及jheatbugs例子的图文攻略
看了很多网上的说明，好像运行都有点问题，自己摸索了下，参照Swarm网站的How to Set Up Java Swarm in Eclipse
-------------------
CLSFractal: Thread mouseClicked
BlankArea:mouseEventDemo mousePressed
Myblack: Graphics Color
MouseEventDemo:MouseListener
barCha:FontMetrics solid Color-Eclipse run java Swarm and jheatbugs read a lot of examples of graphic Raiders online description, it seems to run a little problem, their own way, the reference to the Swarm website How to Set Up Java Swarm in Eclipse------------------- CLSFractal: Thread mouseClicked BlankArea: mouseEventDemo mousePressed Myblack: Graphics Color MouseEventDemo: MouseListener barCha: FontMetrics solid Color
