Java完美实现2048小游戏

1、java完美实现2048小游戏本文给大家分享的是一则根据网友的代码改编的2048小游戏的源码，个人认为已经非常完 美了，推荐给大家，有需要的小伙伴可以参考下。完美地模仿了 2048游戏，是根据网友的一个2048改的。block.javaimport javax.swing. *;import java.awt.*;public class block exte nds j label private int value; public block() value = 0;/初始化值为 0 setfont(new fontc'font", font.plain, 40);/设定

2、字体 setbackground(color.gray);/设定初始颜色为灰色 public int getvalue()获取值 return value; public void setvalue(int value) this.value =value; string text = string.valueof(value);if (value != 0)settext(text); elsesettext("");/如果值为 0 则不显示setcolor(); public void setcolorf) 根据值的不同设定不同的背景颜色、label字体 switch
