How to use Enum name and values methods ?

name() is a static method which returns name of enum.

enum Day {

       SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY;

}

public class EnumTest {

       public static void main(String[] args) {

              Day day1 = Day.MONDAY;

              String dayName1 = (day1.name());

              System.out.println(dayName1);

       }

}

Output

MONDAY

values() returns all enum instances as an array.

enum Shape {

      LINE(1), TRIANGLE(3), RECTANGLE(4), PENTAGON(5);

           private int value;

      // Constructor setting some value

      private Shape(int value) {

          this.value = value;

      }

     @Override

     public String toString() {

         return “Number of lines: “+value;

     }

}

public class EnumTest {

       public static void main(String[] args) {

             Shape[] shapes = Shape.values();

             Shape shape1 = shapes[0];

              System.out.println(shape1.name() + “ ” + shape1);

       }

}

Output

LINE Number of lines: 1
