Hello, the challenge doesn't pass when the method readLine is left with empty parenthesis

This is because the Console object's readLine() method has a parameter of the String type.

In Java, methods have, "method signatures," which must specify the parameters and return type.

Thus, to call Console's readLine() object, we will need to provide the right method signature for our call, which in this case is a parameter of the type String.

Hence, when you want to call the method, readLine(), you have to pass it a string to display to the user. Technically, if you don't want to pass a prompt to the user, you can just pass it an empty string, which is "". Then when the user is prompted, they are shown a blank String.

console.readLine("");

Also note that you must use double-quotes in Java, single-quotes are reserved for a different type, char.

If you write:

Java String example = console.readLine(); then because the readLine method requires parameters in the form of a string, It would cause an exception and crash.

This proper format is you don't want to include a string in a form of and output message would be:

Java String example = console.readLine("");

Having the empty quotation marks states, that there is indeed a string, it just happens to be empty.

I hope this helps you understand.
