The toLowerCase() method is a method of the String class. So it's an inbuilt helper method; i.e. it performs a function that is likely to be required due to the properties of the class. People are likely to want a lower, or upper, case version of any string. Both those methods exist to help with those requirements.

When I wrote the method in IntelliJ IDE, I got "Cannot resolve symbol "toLowerCase' error.

57,712 PointsYes, you would; apologies. It is a method so requires parentheses after it:
.toLowerCase()Steve.
