核心功能说明
🎯 主要特性：
- 多种兵种类型：包含步兵、骑兵、弓箭手、骑士、长枪手、剑士
- 属性系统：每个兵种有不同的生命值、攻击力和防御力
- 战斗模拟： 实时的回合制战斗模拟，包含暴击伤害
- 统计分析：对任意两个兵种进行批量战斗统计
- 可视化输出：详细显示每回合战斗情况
📊 统计维度：
- 胜负率：查看哪个兵种占据优势
- 回合数统计：包含平均、最大、最小回合数
- 伤害统计：可以扩展增加总伤害统计
- 排名：按胜率排序所有对战组合
🔧 使用方法：
# 编译 javac GroundCombatSimulator.java # 运行 java GroundCombatSimulator
📈 预期输出：
========== 地面对抗模拟系统 ==========
模拟兵种: 步兵, 骑兵, 弓箭手, 骑士, 长枪兵, 剑士
每个对战组合模拟次数: 1000
对抗 骑士 VS 步兵: 胜率: 68.5%, 平均回合: 8.2, 最长回合: 15, 最短回合: 5
对抗 剑士 VS 弓箭手: 胜率: 65.2%, 平均回合: 7.8, 最长回合: 14, 最短回合: 5
...这个系统是可扩展的,你可以：
- 添加新的兵种
- 调整属性数值
- 增加战术/地形因素
- 实现不同规模的军队对抗
