I am going through Enums that were introduced in Java 1.5. In Effective Java 2'nd Edition it's mentioned that before Java 1.5 there were int and String enum patterns which were having some deficiencies.

I understood the cons of int enum patterns but while going through String enum patterns I got the basic idea but didn't get the deep sense of below statements mentioned under Item30 in Effective Java:

This variant, known as the String enum pattern, is even less desirable. While it does provide printable strings for its constants, it can lead to performance problems because it relies on string comparisons. Worse, it can lead naive users to hard-code string constants into client code instead of using field names. If such a hard-coded string constant contains a typographical error, it will escape detection at compile time and result in bugs at runtime.

Can anyone help me in understanding what these lines explaining. I would appreciate if it can be explained with some code snippet.

Thanks

Hey man love your videos but I was wondering do you ever do one on one conversation about software engineering? Of course if you’re compensated for your time.

Let’s say you have a enum field that’s part of your api. Would adding a new enum type be considered breaking your api?

If this man makes a course i will be the first to buy!
