How do you retrieve all enumeration values in Java?

In Java, the values() method of the Enum class can be used to retrieve all enum values. This method will return an array containing all the values of the enum type.

Here is a sample code:

enum Color {
    RED, GREEN, BLUE;
}

public class Main {
    public static void main(String[] args) {
        Color[] colors = Color.values();
        for (Color color : colors) {
            System.out.println(color);
        }
    }
}

Output result:

RED
GREEN
BLUE

In the example above, all the values of the Color enum type were obtained using the Color.values() method, and each enum value was printed using a for-each loop.
