Calendar methods doesn't work on netbeans

Question

I'm trying to use some methods that should work in a Calendar, for example :

public void calculaSemanal(){
          CoffeeCalendar coffeeCalendar = CoffeeCalendar.getInstance();
        int week = coffeeCalendar.get(CoffeeCalendar.WEEK_OF_MONTH);
                }

but "create method getInstance()"appears; obs: i have java.util.Calendar imported, JDK version 1.8

Answer 1

Not sure what you're after with CoffeeCalendar, but the java.util.Calendar package does what your code is trying to do:

Calendar c = Calendar.getInstance();
int week = c.get(Calendar.WEEK_OF_MONTH);
