How to handle the ignore case in strings

Hello All,

I am using a Map<string,List<string>> mapEmailtoBodyFields = new Map<string,List<string>>(); to map the email ids to description fields of an object.

Requirement : Have to check whether email id is present in our system. if present I have to do some logic. my question is, when I am comparing email in the map with the email ids in the system (our salesforce org), I might run into a case mismatch. For example:

key in the map : John.Doe@xyz.com
Email Id in the system : john.doe@xyz.com

When I am comparing these two,it should not fail because both the email ids are same. How can I make sure to compare this case sensitivity. I do not need a boolean result because, I am using map.get(emailID) .Please share your thoughts.

You can set both values to all lower case before comparing using String.toLowerCase so you won't have to worry about case. Below link has information on the method.

Yeah. Thanks Terence_Chiu_TCCloudDev. That worked. By default, salesforce stores the email ids in lower case. When I insert email ids to the map, I changed the case to lower.

That was very helpful :)
