Java課程設計-定時器（團隊）

1、團隊介紹（沒頭腦和不高興）

• 陳文俊[組長] 201521123047 網絡1512 宣委

• 鄭子熙 201521123045 網絡1512

2、項目Git連接

定時器

3、項目git提交記錄截圖

4、項目功能架構圖與主要功能流程圖

5、項目運行截圖

界面

輸入時間

運行一段時間後暫停

隱藏倒計時面板

6、程序關鍵代碼

public class Time {

    public static String getTime(int seconds) {
        Integer hours = seconds / 3600;
        Integer minutes = seconds / 60;
        Integer second = seconds % 60;
        String time = "";
        if (minutes >= 60)
            minutes %= 60;
        if (hours < 10)
            time += "0" + hours + " : ";
        else
            time += hours + " : ";
        if (minutes < 10)
            time += "0" + minutes + " : ";
        else
            time += minutes + " : ";
        if (second < 10)
            time += "0" + second;
        else
            time += second;
        return time;

7、尚待改進或者新的想法

界面能夠花時間作得更加美觀，還用圖標來代替按鈕。
