What does the cal.get() method mean?

    public static int getTimesWeekmorning(){

    Calendar cal = Calendar.getInstance(); 
    cal.set(cal.get(Calendar.YEAR),cal.get(Calendar.MONDAY), cal.get(Calendar.DAY_OF_MONTH), 0, 0,0);                              
    cal.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY); 
    return (int) (cal.getTimeInMillis()/1000); 
    }

JavaDocs for [`Calendar#get`](https://docs.oracle.com/javase/8/docs/api/java/util/Calendar.html#get-int-). If possible you should use Java 8's new Time API of Joda-Time instead. In your case, it's just setting the current time of the `Calendar` to midnight of the current day – MadProgrammer Aug 12 '15 at 03:23
@MadProgrammer midnight of the current day? i need the time of the first day of the week. – Brooklyn Knightley Aug 12 '15 at 03:34
Yep, that's kind of what the second `set` statement is doing. The first `set` zeros out the time, set second changes the day of the week to `MONDAY` – MadProgrammer Aug 12 '15 at 03:36
@MadProgrammer how about cal.get(Calendar.MONDAY)? – Brooklyn Knightley Aug 12 '15 at 03:55
What does the JavaDocs tell you? – MadProgrammer Aug 12 '15 at 03:57
Perhaps you should have a look at [this](http://stackoverflow.com/questions/2937086/how-to-get-the-first-day-of-the-current-week-and-month) – MadProgrammer Aug 12 '15 at 03:58
