返回值：如果等於指定的規則，則此方法返回true。

以下示例程序旨在說明WeekFields.equals()方法：
程序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); 
    } 
}

輸出：

Equals:true

程序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); 
    } 
}
