我正在学习构建简单行为Ai的教程.它的"大脑"类是抽象的,包含"跑步","成功","失败"等状态.现在在我的ai单元 - 机器人类我有一个方法来启动机器人的大脑.

    public void update(){

        if(Routine.getState()==null){
            Routine.start();
        }
        Routine.act(this, board);

    }

现在这在java中是不可能的,因为它是对非静态方法的静态引用.我试图在这里引用的例程抽象类是这样的:

public abstract class Routine {

    public enum RoutineState{
        Success,
        Failure,
        Running
    }

    protected RoutineState state;

    protected Routine() { }

    public void start(){
        this.state = RoutineState.Running;
    }

    public abstract void reset();

    public abstract void act(droid droid, board board);

    public void succed(){
        this.state = RoutineState.Success;
    }

    public void Fail(){
        this.state = RoutineState.Failure;
    }

    public boolean isSuccess(){
        return state.equals(RoutineState.Success);
    }

    public boolean isFailure(){
        return state.equals(RoutineState.Failure);
    }

    public boolean isRunning(){
        return …

一个简单的Quote生成器是有问题的,我已经构思了代码,并假设如果我将我的字符串保存在xml中它将起作用

<resources>
    <string name="app_name">"Lift Quote"</string>
    <string name="action_settings">Settings</string>
