Below programs illustrate the WeekFields.equals() method:
Program 1:
// Java program to demonstrate// WeekFields.equals() method  import java.time.DayOfWeek;import java.time.temporal.WeekFields;  public class GFG {    public static void main(String[] args)    {          // create WeekFields        WeekFields weekFields            = WeekFields.of(DayOfWeek.MONDAY, 1);        WeekFields otherWeekFields            = WeekFields.of(DayOfWeek.MONDAY, 1);          // apply equals()        boolean bothAreEquals            = weekFields.equals(otherWeekFields);          // print results        System.out.println("Equals: "                           + bothAreEquals);    }} |
Output:
Equals: true
Program 2:
// Java program to demonstrate// WeekFields.equals() method  import java.time.DayOfWeek;import java.time.temporal.WeekFields;  public class GFG {    public static void main(String[] args)    {          // create WeekFields        WeekFields weekFields            = WeekFields.of(DayOfWeek.MONDAY, 1);        WeekFields otherWeekFields            = WeekFields.of(DayOfWeek.SUNDAY, 3);          // apply equals()        boolean bothAreEquals            = weekFields.equals(otherWeekFields);          // print results        System.out.println("Equals: "                           + bothAreEquals);    }} |
Output:
Equals: false
