java案例统计地面对抗谁胜出？

完整案例：地面对抗模拟系统
核心功能说明

我来提供一个Java程序,模拟地面对抗（比如士兵VS士兵，或者步兵VS骑兵）的胜负统计。

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
