There is a variant of equals() called equalsIgnoreCase() that compares two strings, ignoring uppercase/lowercase differences. Remember: use equals() to compare strings. Objects of different types, except different numeric types, never compare equal.

First, if you take all the Java programs ever written, youll find that about 25 of the objects in them are strings. The equals() method is case-sensitive, meaning that the string "HELLO" is considered to be different from the string "hello".

Comparing strings in Java Why are we considering string comparisons separately from everything else The reality is that strings are a subject in their own right in programming.
