How do I case-insensitively check for equality?

Question

When I use if/else I want the if to be case-insensitive. So instead of having to type "What's Up", "what's up", "What's up", "What's UP", et cetera, I can make it case insensitive and only use one variation of "what's up".

Which language? Give an example. What have you tried so far? — m02ph3u5, Aug 23 '15 at 17:47

Make everything lower case or uppercase and compare or use a native case-insensitive function for camparison (if available). — m02ph3u5, Aug 23 '15 at 18:14

Convert the string to lower case (or upper case), and then compare:

>>> s = "What's Up"
>>> s.lower() == "What's up".lower()
True

In any language, just make the text entered to be lowercase first and then compare it in the if/else block.

In java, you can store the value in a string and use the equalsIgnoreCase() method to compare values in if/else block.

Go to this link: equalsIgnoreCase

Search for equalsIgnoreCase() method on this page

Check below link:

Hope this helps
