Setting First Day of Week in a Current Dated Calendar Instance Example
The following example shows the usage of Java Calendar setFirstDayOfWeek(value) method. We're creating an instance of a Calendar of current date and print the first day of the week then using setFirstDayOfWeek() method, we're altering the first day of the week and print the altered one.
package com.tutorialspoint; import java.util.Calendar; public class CalendarDemo { public static void main(String[] args) { // create a calendar Calendar cal = Calendar.getInstance(); // print current first day of the week int day = cal.getFirstDayOfWeek(); System.out.println("Current first day of the week:" + day); // set first day of the week as something else cal.setFirstDayOfWeek(Calendar.WEDNESDAY); // print altered first day of the week day = cal.getFirstDayOfWeek();; System.out.println("Altered first day of the week:" + day); } }
Output
Let us compile and run the above program, this will produce the following result −
Current first day of the week:1 Altered first day of the week:4
Setting First Day of Week in a Calendar Instance with GB locale Example
The following example shows the usage of Java Calendar setFirstDayOfWeek(value) method. We're creating an instance of a Calendar of current date using an en locale and print the first day of the week then using setFirstDayOfWeek() method, we're altering the first day of the week and print the altered one.
package com.tutorialspoint; import java.util.Calendar; import java.util.Locale; public class CalendarDemo { public static void main(String[] args) { // create a calendar Calendar cal = Calendar.getInstance(new Locale("en", "GB")); // print current first day of the week int day = cal.getFirstDayOfWeek(); System.out.println("Current first day of the week:" + day); // set first day of the week as something else cal.setFirstDayOfWeek(Calendar.WEDNESDAY); // print altered first day of the week day = cal.getFirstDayOfWeek();; System.out.println("Altered first day of the week:" + day); } }
Output
Let us compile and run the above program, this will produce the following result −
Current first day of the week:2 Altered first day of the week:4
Setting First Day of Week in a Calendar Instance with CA locale Example
