如何使用Informatica中的星期数来计算星期一的星期一日期？

Answer 1

// We know week number and year. 
int week = 42; 
int year = 2014; 

// Get calendar, clear it and set week number and year. 
Calendar calendar = Calendar.getInstance(); 
calendar.clear(); 
calendar.set(Calendar.WEEK_OF_YEAR, week); 
calendar.set(Calendar.YEAR, year); 

// Now get the first day of week. 
Date date = calendar.getTime();
