Is Java map get case-sensitive?

Two choices come to my mind:

Java String equalsIgnoreCase() Method The equalsIgnoreCase() method compares two strings, ignoring lower case and upper case differences. This method returns true if the strings are equal, and false if not. Tip: Use the compareToIgnoreCase() method to compare two strings lexicographically, ignoring case differences.

Map is one of the most common data structures in Java, and String is one of the most common types for a map’s key. By default, a map of this sort has case-sensitive keys .26 May 2020

Map uses equals and hashCode to test for key equality, and you can’t overwrite these for String . What you could do is define your own Key class which contains a string value, but implements equals and hashCode in a case insensitive way.
