This is not a good question, it forces people to use this ancient calendar class from the 90s back when java was 1.1.
instead use the localDate class. We're in 2021 and java 15 is here. why should we use this ancient tools to solve problems.

import java.time.LocalDate; // write this part. this is very important and in order to use it you have to change from java 7 to java 8 in the editor.


public static String findDay(int month, int day, int year) {
LocalDate date = LocalDate.of(year, month, day);
String str =
return str;
}

import java.time.LocalDate;
class Result {




public static String findDay(int month, int day, int year) {
return LocalDate.of(year, month, day).getDayOfWeek().name();

}

}

how did you make changes to all 'calender' word at once?

My Solution is the below one

// public static String findDay(int month, int day, int year) {
// Calendar cal=Calendar.getInstance();

// cal.set(Calendar.MONTH, month-1);
// cal.set(Calendar.DAY_OF_MONTH, day);
// cal.set(Calendar.YEAR, year);
// String dayOfWeek=cal.getDisplayName(month, day, Locale.ROOT).toUpperCase();
// return dayOfWeek;
//
The program's solution in the video throws: -
