Question

我有10个通用代理：

public class Agent {
    private Context<Object> context;
    private Geography<Object> geography;
    public int id;
    public boolean isFemale;
    public double random;


public Agent(Context<Object> context, Geography<Object> geography, boolean isFemale, double random) {
    this.context = context;
    this.geography = geography;
    this.isFemale = isFemale;
    this.random = random;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public boolean isFemale() {
    return isFemale;
}

public void setFemale(boolean isFemale) {
    this.isFemale = isFemale;
}

public double getRandom() {
    return random;
}

public void setRandom(double random) {
    this.random = random;
}

public void methods  {

... does things
}

代理商是在地理环境（纬度和经度）中创建的。我试图建立我的代理人随机男性或女性。我在上下文构建器中用于创建代理的代码如下：

    Agent agent = null;
    boolean isFemale = false;
    for (int i = 0; i < 10; i++) {
        double random = RandomHelper.nextDoubleFromTo(0, 1);
        if (random > 0.33){
            isFemale = true;
        }
        agent = new Agent(context, geography, isFemale, random);
        context.add(agent);
        Coordinate coord = new Coordinate(-79.6976, 43.4763);
        Point geom = fac.createPoint(coord);
        geography.move(agent, geom);
    }

当我测试代码时，我发现他们都是女性。我究竟做错了什么？如果有的话，我会认为他们都是男性，因为布尔值默认为假。

Answer 1

boolean一旦变为isFemale = true，每次迭代都不会更新false，其他值仍然适用。您可以添加其他部分来设置for (int i = 0; i < 10; i++) { isFemale = false;//Set it here double random = RandomHelper.nextDoubleFromTo(0, 1); if (random > 0.33){ isFemale = true; //...。

if (random > 0.33){
   isFemale = true;
} else {
   isFemale = false;
}

<强> OR

agent = new Agent(context, geography, random > 0.33, random);

<强> OR

{{1}}

Answer 2

因为一旦你的布尔值设置为true，它就会保持这种状态（你永远不会将它设置为false，它只是if的一个分支）。

BTW，抓问题标题
