I was curious why the class java.lang.String is defined as final in Java when I first learned about it. I couldn't find an answer back then, but check out this post: How to Create a Java String Class Replica. It reminded me of my question.
Sure, String gives all the functionality I've ever required, and I've never considered any action that would necessitate an extension of class String, but you never know what someone could demand!
So, does anyone know what the designers were thinking when they chose to make it final?
Scaler's blog advised me to consider the proliferation of "need a few more utility methods on String" projects that would emerge - all of which could not utilize each other's Strings since they were of a different class.
