Getting error after running boolean check

Hi after running Boolean check within the java-repl screen it returns true as expected but then any further commands or check that are carried out return error. see below. Why has it become an error running this check and how is this resolved without closing and reopening the screen.

Hi Rehan!

Looks like you found a little bug in the REPL. When you typed:

 boolean= someWords.contains("This")

You forgot the variable name...I think you created a boolean named boolean which isn't allowed in Java, but somehow the REPL let you do it ;)

Try it again with a valid variable name like this:

boolean doesItHaveWord = someWords.contains("This");
