Patterns/Anti-patterns

Constants

Use a class that cannot be instantiated for the use of constants.

Using an interface is an anti-pattern because of what an interface implies.

/**
 * It should also be final, else we can extend this and create a constructor allowing us to instantiate it anyway.
 */
public final class Constants {
    private Constants() {} // we should not instantiate this class

    public static final String HELLO = "WORLD";
    public static final int AMOUNT_OF_CONSTANTS = 2;
}
