在主类中启动新线程的Java类

Question

I'm trying to write a library for my users, and would like it to be as easy to use as possible. Right now, to use it, you have to start a new thread, and set a lot of variables to track, in your main class, however my users are not always experienced in Java, and threading might be too hard for some of my users.

So I want to move the entire threading into my class, and allow users to call a function, to start the thread.

Here is the thread I'm currently running in the main class:

int valueToAdd = 0;

DreamStatsTracker tracker = new DreamStatsTracker();

StartSessionResponse response = tracker.StartSession("ae-13s-90-11", "Abe");

System.out.println(response.getMessage());

System.out.println("Adding skill Herblore");

String message = tracker.AddSkill(response.getSessionId(), Skill.HERBLORE, "Abe");

Thread thread = new Thread(() -> {  
  while(true) {
    tracker.SetValueForSkill(response.getSessionId(), Skill.HERBLORE, valueToAdd);
  }
});

I would like to move that entire thing into the DreamStatsTracker class, and do something like this from the main class:

DreamStatsTracker tracker = new DreamStatsTracker();

tracker.AddSkill(Skill1, ValueForSkill1);

tracker.AddSkill(Skill2, ValueForSkill2);

tracker.Start();

This would start a new instance of the DreamStatsTracker , which would start a new thread, and track the values of the added skills continuously in the background, while the main class is running.

How would I approach this, and is it even possible?

I finally solved my issue, by hours of testing and trying.

This is what I did:

Tracker class:

Thread mainThread;

public DreamStatsTracker(){
    mainThread = new Thread(() -> {
        while(true){
            for (SkillAndValue skillAndValue : Skills) {
                try {
                    SetValueForSkill(this.SessionId, skillAndValue.getSkill(), skillAndValue.getValue());
                    System.out.println("Added value: " + skillAndValue.getValue());
                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            try {
                Thread.sleep(2000);
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    });

}

public void AddSkillAndValue(Skill Skill, Callable<Integer> function) throws Exception{
    Skills.add(new SkillAndValue(Skill, function));
}

public void Start(){
    for (SkillAndValue skillAndValue : Skills) {
        AddSkill(this.SessionId, skillAndValue.getSkill(), this.Username);
    }
    this.mainThread.start();
}

This is the main class:

public static void main(String[] args) throws Exception {

    DreamStatsTracker tracker = new DreamStatsTracker();

    tracker.StartNewSession("ae-13s-90-11", "Abe");

    tracker.AddSkillAndValue(Skill.HERBLORE, getRandomNumber());

    tracker.Start();

}

private static Callable<Integer> getRandomNumber(){
    return new Callable<Integer>(){
        public Integer call(){
            Random random = new Random();
            return random.nextInt(10000);
        }
    };
}
