java中計算兩個時間相差多少分鐘 具體程式碼如下： public static String getDatePoor(Date endDate, Date nowDate) { long nd = 1000 * 24 * 60 * 60; long nh = 1000 * 60 * 60; long nm = 1000 * 60; // long ns = 1000; // 獲得兩個時間的毫秒時間差異 long diff = endDate.getTime() - nowDate.getTime(); // 計算差多少天 long day = diff / nd; // 計算差多少小時 long hour = diff % nd / nh; // 計算差多少分鐘 long min = diff % nd % nh / nm; // 計算差多少秒//輸出結果 // long sec = diff % nd % nh % nm / ns; return day + "天" + hour + "小時" + min + "分鐘"; } data預設有toString() 輸出格林威治時間，比如說Date date = new Date(); String toStr = date.toString();
