**`EnumSet`** is similar to `Set`, except that `EnumSet` only contains the `enum` type as elements. All the elements must be from a single `enum` type. For further details on `EnumSet`, refer to this [shot](https://www.educative.io/answers/what-is-an-enumset-in-java).

The **`size` method** can be used to get the number of elements present in the `EnumSet` object. 

#   
## Syntax

```java
public int size()
```

## Parameters
This method doesn't take any parameters.

## Return value
The `size()` method returns the integer value that represents the number of elements present in the `EnumSet`.

## Code

import java.util.EnumSet;
class SizeExample {
    enum Size {
        SMALL, MEDIUM, LARGE, EXTRALARGE
    }
    public static void main( String args[] ) {
        EnumSet<Size> set = EnumSet.allOf(Size.class);
        System.out.println("The set is " + set);
        System.out.println("\nThe size is " + set.size());
    }
}

#   
## Explanation

In the code above:

* *In line 1*: Import the `EnumSet` class.

* *In line 3*: We create an `Enum` with the name `Size`.

* *In line 7*: We use the `allOf` method to create a new `EnumSet` object. The returned object will contain all of the elements in the specified element type. In our case, the returned `set` contains all the elements of the `Size` enum. 

* *In line 9*: We use the `size` method to get the number of elements present in the `set`. In our case, the code will return `4`.

What is the EnumSet.size method in Java? 

EnumSet.size method returns the count of elements in an EnumSet, which contains elements of a single enum type.
