To remove elements from an EnumMap in Java, you can use the remove() method. Here's an example that demonstrates how to remove a key-value pair from an EnumMap:

import java.util.EnumMap;

enum Color {
    RED, GREEN, BLUE;
}

public class Example {
    public static void main(String[] args) {
        EnumMap<Color, Integer> colorMap = new EnumMap<>(Color.class);

        colorMap.put(Color.RED, 1);
        colorMap.put(Color.GREEN, 2);
        colorMap.put(Color.BLUE, 3);

        System.out.println(colorMap);

        colorMap.remove(Color.GREEN);

        System.out.println(colorMap);
    }
}

In this example, we first define an enum called Color, which has three values: RED, GREEN, and BLUE. We then create a new EnumMap object that maps Color keys to Integer values. We use the put() method to insert key-value pairs into the EnumMap.

To remove an element from the EnumMap, we call the remove() method, passing in the key for the element we want to remove. In this case, we remove the element associated with the GREEN key.

After removing the element, we print out the contents of the EnumMap using the toString() method again. This will output the following:

{RED=1, GREEN=2, BLUE=3}
{RED=1, BLUE=3}

As you can see, the GREEN key-value pair has been removed from the EnumMap.
