如何获得周数。 （我有约会）？

Question

我目前正在开发一个需要查找给定日期的周数的项目。

你可以给我一个代码片段来解决我的问题吗？

感谢。

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

这可以解决您使用此问题：

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