Question

如何在java中组合boolean和非布尔if语句？是否需要编写条件语句的特定方式？

例如，下面的代码每次给我不同的结果。

甲虫被初始化为随机的男性或女性，年龄为0岁。

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：

...上下文

    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sysout代码，看到我确实得到了雄性和雌性甲虫。我也有sysout代码，看他们正在老化。

有时会跳过方法，就好像条件不满足一样。有时它们都能正常工作。

很抱歉，输出采用代码格式，但最简单。我想要的是，如果甲虫是7岁和女性，他们会找到一个伴侣。如果甲虫是13岁和男性，他们将死亡。如果甲虫年龄25岁，女性，他们将死亡。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

Answer 1

这里有点延迟，但问题已经解决in conversation with Nick Collier, Repast Simphony co-creator on the repast interest list。他表示，所有方法都安排在相同的优先级，这意味着他们使用随机助手（因此随机种子）来决定他们的顺序。

因此，例如，可以在step()等之后调用checkMate()，然后在下一个标记中，再次发生随机化，并且可以在{{1}之前调用step()结果当代理为13时，代理可能是13然后是14而没有任何其他方法被调用。如果要指定checkMate()方法的优先级，可以使用优先级参数或者只是交错开始时间（即@Scheduled从step()开始，然后是1的下一个方法，依此类推。）

如果1.1方法是最高优先级，我发现我的代码工作正常。
