java实现连续签到加分_java实现app签到功能

实现连续签到加分的Java代码可以参考以下示例：

// 定义签到记录类
public class SignInRecord {
    private Date signInDate;
    private int signInScore;

    public SignInRecord(Date signInDate, int signInScore) {
        this.signInDate = signInDate;
        this.signInScore = signInScore;
    }

    public Date getSignInDate() {
        return signInDate;
    }

    public int getSignInScore() {
        return signInScore;
    }
}

// 定义签到管理类
public class SignInManager {
    private List<SignInRecord> signInRecords;
    private int maxContinuousDays; // 最大连续签到天数
    private int continuousDays; // 当前连续签到天数
    private int signInScore; // 签到得分

    public SignInManager() {
        signInRecords = new ArrayList<>();
        maxContinuousDays = 0;
        continuousDays = 0;
        signInScore = 0;
    }

    public void signIn() {
        Date today = new Date();
        int score = 1;
        if (!signInRecords.isEmpty()) {
            // 判断是否连续签到
            Date lastSignInDate = signInRecords.get(signInRecords.size() - 1).getSignInDate();
            if (isContinuousSignIn(lastSignInDate, today)) {
                continuousDays++;
                score = continuousDays;
                if (continuousDays > maxContinuousDays) {
                    maxContinuousDays = continuousDays;
                }
            } else {
                continuousDays = 1;
            }
        }
        signInRecords.add(new SignInRecord(today, score));
        signInScore += score;
    }

    public int getMaxContinuousDays() {
        return maxContinuousDays;
    }

    public int getContinuousDays() {
        return continuousDays;
    }

    public int getSignInScore() {
        return signInScore;
    }

    // 判断是否连续签到
    private boolean isContinuousSignIn(Date lastSignInDate, Date today) {
        Calendar lastCal = Calendar.getInstance();
        lastCal.setTime(lastSignInDate);
        int lastYear = lastCal.get(Calendar.YEAR);
        int lastDayOfYear = lastCal.get(Calendar.DAY_OF_YEAR);
        Calendar todayCal = Calendar.getInstance();
        todayCal.setTime(today);
        int todayYear = todayCal.get(Calendar.YEAR);
        int todayDayOfYear = todayCal.get(Calendar.DAY_OF_YEAR);
        return lastYear == todayYear && todayDayOfYear - lastDayOfYear == 1;
    }
}

实现App签到功能的Java代码可以参考以下示例：

// 定义签到记录类
public class SignInRecord {
    private Date signInDate;

    public SignInRecord(Date signInDate) {
        this.signInDate = signInDate;
    }

    public Date getSignInDate() {
        return signInDate;
    }
}

// 定义签到管理类
public class SignInManager {
    private List<SignInRecord> signInRecords;

    public SignInManager() {
        signInRecords = new ArrayList<>();
    }

    public void signIn() {
        Date today = new Date();
        signInRecords.add(new SignInRecord(today));
    }

    public int getSignInCount() {
        return signInRecords.size();
    }

    public boolean hasSignedInToday() {
        if (signInRecords.isEmpty()) {
            return false;
        }
        Date lastSignInDate = signInRecords.get(signInRecords.size() - 1).getSignInDate();
        Calendar lastCal = Calendar.getInstance();
        lastCal.setTime(lastSignInDate);
        int lastYear = lastCal.get(Calendar.YEAR);
        int lastDayOfYear = lastCal.get(Calendar.DAY_OF_YEAR);
        Calendar todayCal = Calendar.getInstance();
        int todayYear = todayCal.get(Calendar.YEAR);
        int todayDayOfYear = todayCal.get(Calendar.DAY_OF_YEAR);
        return lastYear == todayYear && lastDayOfYear == todayDayOfYear;
    }
}

这两份代码仅供参考，实际应用中还需要根据业务需求进行相应的调整和优化。
