java的面向对象和类

平均步数的方法怎么写呀
如何在不添加别的方法的情况下获取总步数

public static class StepTracker {
    private int minStep;
    private int addDailySteps;
    private int days;
    private int activeDays;
    
    public StepTracker(int minStep) {
        this.minStep = minStep;
    }
    public void addDailySteps(int dailySteps) {
        addDailySteps += dailySteps;
        if (dailySteps >= minStep) {
            activeDays++;
        }
        days++;
    }
    public int activeDays() {
        return activeDays;
    }
    public int averageSteps() {
        return days == 0 ? 0 : addDailySteps / days;
    }
}
