java中的组合boolean和非布尔if语句如何工作？是否需要编写条件语句的特定方式？

例如，下面的代码每次都会给我不同的结果。

甲虫随机初始化为雄性或雌性，年龄为 0。

public class BeetleAgent {
    public boolean isFemale;
    public int age;

    public BeetleAgent(boolean isFemale, int age) {
        // initialize class variables with arguments
    } 

    //age in days
    @ScheduledMethod(start = 1, interval = 1)
    public void trackAge () {
        this.setAge(getAge() + 1);
        System.out.println("Beetle is now " + this.getAge());

    }

    // adults mate after 1 week 
    @ScheduledMethod(start = 1, interval = 1)
    public void checkMate() { 
        if (this.getAge()== 7 && this.isFemale()) {
            System.out.println("Both are true, beetle can MATE.");
            mate();
        }
    }

    @ScheduledMethod(start = 1, interval = 1)
    public void checkMaleDeath() { 
        if (!this.isFemale() && this.getAge()== 13) {
            System.out.println("Both are true, male beetle can DIE.");
            maleDeath();
        }   
    }

    @ScheduledMethod(start = 1, interval = 1)
    public void checkFemaleDeath() {
        if (this.isFemale() && this.getAge() == 25) {
            System.out.println("Both are true, female beetle can DIE.");
            femaleDeath();
        }
    }

    // getters and setters
}

我无法想象java不允许混合......

编辑：

语境...

    Random random = new Random();
    for (int i = 0; i < 6; i++) {
        boolean isFemale = random.nextBoolean();
        int age = 0;
        BeetleAgent beetle = new BeetleAgent(context, geography, isFemale, age);
        context.add(beetle);
        beetleagentlist.add(beetle);
        Coordinate coord = new Coordinate(-79.6976, 43.4763);
        Point geom = fac.createPoint(coord);
        geography.move(beetle, geom);
    }

我有系统输出代码，可以看到我确实得到了雄性和雌性甲虫。我也有 sysout 代码来查看它们是否正常老化。

有时，方法会被跳过，就好像条件不满足一样。有时它们都可以正常工作。

抱歉，输出是代码格式，但它最简单。我想要的是，如果甲虫是 7 岁的雌性，它们会找到配偶。如果甲虫年龄为 13 岁且为雄性，它们将死亡。如果甲虫年龄为 25 岁且为雌性，它们将死亡。有时会发生这种情况：

Sometimes this happens, where for in this example, but females dont die(not good). Also notice that the mate function only ran once as it should:
Female: false
Female: false
Female: false
Female: true
Female: true
Female: true

这里有点延迟，但问题已在与就餐兴趣列表上的 Repast Simphony 共同创建者 Nick Collier 的对话中得到解决。他说所有方法都被安排为相同的优先级，这意味着它们使用随机助手（因此是随机种子）来决定它们的顺序。

因此，例如，step()可能在checkMate()等之后被调用，然后在下一个滴答中，随机化再次发生并且step()可能在之前checkMate()等被调用。因此，代理可能是 13，然后是 14，而当代理时没有调用任何其他方法是 13。如果你想指定@Scheduled方法的优先级，你可以使用优先级参数或者只是错开开始时间（即step()从 开始1，然后下一个方法在1.1等等。）

我发现如果death()方法是最高优先级，我的代码可以正常工作。
