When it comes to comparing enum constants, you have two options. You can use the “==” operator or the “equals” method to check the equality of the enums. Here are a few reasons why using the “==” operator is generally considered to be a better approach to check the enums:

  • Performance: Using the “==” operator is generally faster than using the “equals” method to compare enums in Java. Because it does not involve any method calls or object allocation. The “==” operator simply checks if two references point to the same object in memory. This is a quick and easy operation. On the other hand, the “equals” method compares the values of the objects. This can be more expensive. In specific cases like this one, equals uses “==” operator internally. However, by using “==” operator…
