(1)你可以选择两种玩法,与电脑,或对局 (2)游戏开始时,有两种选择但只能玩对局的,要不右边的棋子不能 　　被选中,(是电脑的棋子) (3)想操纵左边棋子的朋友可以按 E,D,S,F键移动一个矩形光标. 光标包围自己的棋子时,可以按空格键,选中它,然后在一个没有 　　棋子的点按上空格键,即可移动棋子,小心!!!不要对方把您的棋 　　子吃掉了,如果您把对方的棋子都吃掉了,或者对方的棋子被您的棋 　　子包围了,使对方不能移动自己的棋子了,您就赢了这盘棋反之， 　　则输了这盘棋. 操纵右边棋子的朋友,可按 Up,Down,Left,Right键移动棋子,按Enter 键选中棋子. (4)游戏规则: 1.您不能操纵对方的棋子 2.移动棋子时,起点到终点所成的直线中不能有其它任何棋子,否则 　　　就不能移动棋子. 3.起点到终点形成的直线必须是棋盘上的某条直线,否则不能移动 　　　棋子. 4.吃掉对方棋子的情况(满足如下关系) A B A B A B 则棋子B(第一种情况吃掉一个棋子,第二种情况吃掉两个棋子)被吃掉了 (5)可按Esc键退出游戏

1.根据给定汉字值得到汉字拼音,五笔,笔顺,和笔画数 2.要所给定汉字的索引值得到汉字拼音,五笔,笔顺,和笔画数 3.可直接导入GB2312Helper.jar包使用，或修改代码实现更多功能 示例 public static void main(String args[]) { GB2312Helper helper = GB2312Helper.singleton(); GB2312Record record = helper.getRecord('我'); if (record != null) { System.out.println(record.getValue() + " " + record.getPingyin() + " " + record.getBishun()); } else { System.out.println("null"); } String info = "测试汉字拼音和五笔"; GB2312Record rcds[] = helper.getRecords(info); String pingyin = helper.getPingyin(rcds); System.out.println(pingyin); } 输出: 我 wo3 3121534 ce4shi4han4zi4pin1yin1he2wu3bi3

GBK汉字库 1.整合6763个GB2312个汉字 2.整合GBK/3,GBK/4协议共21003个汉字 3.五笔,拼音,和汉字结构等基本属性 4.已生成了GBKHelper.jar包,可直接使用或修改源代码实现更多功能 示例程序: long lasttick = System.currentTimeMillis(); GB2312Helper gb2312Helper = GB2312Helper.singleton(); String info1 = "测试汉字拼音和五笔"; CharacterRecord recs1[] = gb2312Helper.getRecords(info1); String rlt1 = gb2312Helper.getPingyin(recs1); long curtick = System.currentTimeMillis(); System.out.println("=======GB2312用时:=======" + (curtick - lasttick)); System.out.println(rlt1); System.out.println("size=" + GB2312Helper.singleton().getRecordSize()); long lasttick2 = System.currentTimeMillis(); GBKHelper gbkHelper = GBKHelper.singleton(); String info2 = "测试汉字拼音和五笔 龍齏"; CharacterRecord recs2[] = gbkHelper.getRecords(info2); String rlt2 = gbkHelper.getPingyin(recs2); long curtick2 = System.currentTimeMillis(); System.out.println("=======GBK用时:=======" + (curtick2 - lasttick2)); System.out.println(rlt2); System.out.println("size=" + GBKHelper.singleton().getRecordSize()); =======GB2312用时:=======281 ce4shi4han4zi4pin1yin1he2wu3bi3 size=6763 =======GBK用时:=======140 ce4shi4han4zi4pin1yin1he2wu3bi3 long2ji1 size=20923
