What I have tried:

void move(){
        System.out.println("RrrrrRrrrRrrRrrrrrrr");
    }

void move(){
        System.out.println("vroom vroom");
    }

void move(){
        System.out.println("Sploosh Splash");
    }

In the assertEquals calls, you are systematically trying to compare Strings with void function return values. That is a nonsense and the compiler is making you aware of.
In order to fix the code, you could, for instance, replace

Quote:
void move(){
System.out.println("vroom vroom");
}

with

Java

String move(){
        return "vroom vroom";
    }

and so on.

We can't tell: we don't even know which line is line 18, much less what you did above it which is probably where the actual problem is.

You should expect to get syntax errors every day, probably many times a day while you are coding - we all do regardless of how much experience we have! Sometimes, we misspell a variable, or a keyword; sometimes we forget to close a string or a code block. Sometimes the cat walks over your keyboard and types something really weird. Sometimes we just forget how many parameters a method call needs.

We all make mistakes.

And because we all do it, we all have to fix syntax errors - and it's a lot quicker to learn how and fix them yourself than to wait for someone else to fix them for you! So invest a little time in learning how to read error messages, and how to interpret your code as written in the light of what the compiler is telling you is wrong - it really is trying to be helpful!

So read this: How to Write Code to Solve a Problem, A Beginner's Guide Part 2: Syntax Errors[^] - it should help you next time you get a compilation error!
