如何獲得周數。 （我有約會）？

Question

我目前正在從事一個需要查找給定日期的星期數的項目。

您能為我的問題提供一個代碼段嗎？

謝謝。

Answer 1

你可以試試這個

Calendar now = Calendar.getInstance();


  now.set(Calendar.YEAR,2013);
  now.set(Calendar.MONTH,04);//0- january ..4-May
  now.set(Calendar.DATE, 04);

System.out.println("Current week of month is : " +
            now.get(Calendar.WEEK_OF_MONTH));

System.out.println("Current week of year is : " +
            now.get(Calendar.WEEK_OF_YEAR));

Answer 2

這樣可以解決您的問題：

Calendar cal = Calendar.getInstance();
cal.setTime(date);
int weekOfYear = ca.get(Calendar.WEEK_OF_YEAR);
