如何获得周数。 （我有约会）？

Question

我目前正在从事一个需要查找给定日期的星期数的项目。

您能为我的问题提供一个代码段吗？

谢谢。

Answer 1

你可以试试这个

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

这样可以解决您的问题：

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