What is StringUtils.endsWithIgnoreCase in Java?
Overview
endsWithIgnoreCase is a static method of the StringUtils class that checks if the given string ends with the given string/suffix. This method is case-insensitive when comparing the suffix with the end of the string.
Some special cases to look out for are:
- The method returns
truewhen the input string and the suffix arenull. Twonullreferences are considered to be equal. - The method returns
falsewhen the input string isnullor the suffix isnull.
Note: For case-sensitive comparison, refer StringUtils.endsWith

You can import the StringUtils class as follows:
