How do I save WEEK_OF_YEAR as a variable

Question

I'm trying to save WEEK_OF_YEAR so that I can compare it against other WEEK_OF_YEAR, and I tried using Integer.toString(cl.WEEK_OF_YEAR) = currentweek where current week is the string and cl is the calender name. I get an error
unexpected type
required: variable
found: value

I tried defining cl.WEEK_OF_YEAR=intcurrentweek where intcurrentweek is an integer, but it still doesn't work.
After checking online WEEK_OF_YEAR should be an integer, so I'm not sure why I can't save it as a string or integer. what should I do?

Answer 1

cl.WEEK_OF_YEAR is just ID of this property, and is final, you can't change it
// cl.WEEK_OF_YEAR = intCurrentWeek; //error

notice: == compare; = assign
this is assign value to value, it's wrong :
// Integer.toString(cl.WEEK_OF_YEAR) = currentWeek; //error
--------------

Calendar cl = Calendar.getInstance();
String strCurrentWeek = "16";
int intCurrentWeek = cl.get(Calendar.WEEK_OF_YEAR);

// use .equals() to safe compare Strings
boolean res = Integer.toString(intCurrentWeek) .equals(strCurrentWeek);
System.out.println(res);
