写一段根据数据统计奥运男女比例的java代码

public class Olympics {
public static void main(String[] args) {
int maleCount = 0;
int femaleCount = 0;
int totalCount = 100;
// 遍历所有选手
for (int i = 0; i < totalCount; i++) {
// 根据选手性别分别计数
if (isMale(i)) {
maleCount++;
} else {
femaleCount++;
}
}
// 计算男女比例
float maleRate = (float)maleCount / totalCount;
float femaleRate = (float)femaleCount / totalCount;
// 输出男女比例
System.out.println("男性比例: " + maleRate);
System.out.println("女性比例: " + femaleRate);
}
// 判断选手是否为男性
private static boolean isMale(int i) {
// 省略具体判断逻辑
return true;
}
}
