Java Enum values()

In Java, the values() method is a member of the Enum class, which is the superclass of all enum types. The values() method returns an array of the enum type's values in the order they are declared.

Here's an example of how to use the values() method with an enum in Java:

public enum Size {
    SMALL("S"), MEDIUM("M"), LARGE("L"), EXTRA_LARGE("XL");

    private String abbreviation;

    private Size(String abbreviation) {
        this.abbreviation = abbreviation;
    }

    public String getAbbreviation() {
        return abbreviation;
    }

    public static void main(String[] args) {
        Size[] values = Size.values();
        for (Size size : values) {
            System.out.println(size);
        }
    }
}

In this example, the Sizeenum has four constant values: SMALL, MEDIUM, LARGE, and EXTRA_LARGE. The values() method is called to get an array of all the enum values, and the array is assigned to the values variable.

The for loop iterates over the elements of the values array and prints each enum value. The toString() method is called implicitly on each enum value, and the String representation of the value is printed.

You can use the values() method to get an array of the enum type's values in the order they are declared. The values() method is useful for iterating over all the values of an enum type or for accessing a specific value by its position in the array.
