如何在AndroidStudio中檢查變數是否第一次設定為特定值？-有解無憂

我正在嘗試實作一種升級型別的東西。因此，我想檢查第一次更改“mLevel”變數的時間。例如，第一次是 1 到 2，或 2 到 3。

public class UserModel {
    private static int mExperience;
    private static int mLevel;

    public int getExperience() {
        return mExperience;
    }

    public void setExperience(int experience) {
        mExperience = experience;
    }

    public int getLevel() {
        return mLevel;
    }

    public void setLevel(int experience) {
        if(experience < 80){
            mLevel = 1;
        }else if(experience >= 80 && experience <270){
            mLevel = 2;
        }else if(experience >= 270 && experience <640){
            mLevel = 3;
        } else if(experience >= 640 && experience <1250){
            mLevel = 4;
        }else if(experience >= 1250 && experience <2160){
            mLevel = 5;
        }else if(experience >= 2160 && experience <3430){
            mLevel = 6;
        }else if(experience >= 3430 && experience <5120){
            mLevel = 7;
        }else if(experience >= 5120 && experience <7290){
            mLevel = 8;
        }else if(experience >= 7290 && experience <10000){
            mLevel = 9;
        }else{
            mLevel = 10;
        }
    }
}

我添加了一個名為“hLevel”的變數并添加了一個 if 檢查，它檢查 hLevel 是否低于 mLevel。如果是這種情況，它會將變數更新為 mLevel，您可以在這種情況下執行您的操作或呼叫方法。

 public class UserModel {
private static int mExperience;
private static int mLevel;
private static int hLevel

public int getExperience() {
    return mExperience;
}

public void setExperience(int experience) {
    mExperience = experience;
}

public int getLevel() {
    return mLevel;
}

public void setLevel(int experience) {
    if(experience < 80){
        mLevel = 1;
    }else if(experience >= 80 && experience <270){
        mLevel = 2;
    }else if(experience >= 270 && experience <640){
        mLevel = 3;
    } else if(experience >= 640 && experience <1250){
        mLevel = 4;
    }else if(experience >= 1250 && experience <2160){
        mLevel = 5;
    }else if(experience >= 2160 && experience <3430){
        mLevel = 6;
    }else if(experience >= 3430 && experience <5120){
        mLevel = 7;
    }else if(experience >= 5120 && experience <7290){
        mLevel = 8;
    }else if(experience >= 7290 && experience <10000){
        mLevel = 9;
    }else{
        mLevel = 10;
    }
    if (hLevel<mLevel) {
        //Current highest
        hLevel = mLevel;
    }
}
}
