How to get the week of the year for the given date in Java

Especially in English-speaking countries, the use of the calendar week is very common. The calculation and conversion are done with the class LocalDate in Java 8 and with Calendar in Java before version 8.

Let’s see how we can get the week of the year for the given date in Java by using the Calendar class:

//Get the date in the first weeks of a year 
public static int getWeekOfYear(Date date){
    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    int week_of_year = cal.get(Calendar.WEEK_OF_YEAR);
    return week_of_year;
}
