沒(méi)技術(shù)含量，由NetBeans直接生成，嘿嘿
思路：
創(chuàng)建一個(gè)Jbutton，設(shè)置鼠標(biāo)Entered事件，如果事件發(fā)生，那么Jbutton.setLocation(x,y);即更改位置
x,y值是2個(gè)隨機(jī)數(shù)
那么就是Math.random();生成一個(gè)隨機(jī)數(shù)(0-1之間的double數(shù)),乘以666強(qiáng)制轉(zhuǎn)換(int)之后傳入Jbutton.setLocation(x,y);即可。
(Done)?
沒(méi)有所謂的命運(yùn)，只有不同的選擇！
