What is equalsIgnoreCase() in Java?

The equalsIgnoreCase() is a string method in Java. This function is used to compare this string with an input string.

The equalsIgnoreCase() returns true if the length and the corresponding characters are equal but it is case-insensitive. Otherwise, it returns false.
