I cant Complete the lab.I dont know what is wrong with the codeimage1.jpgimage1(1).jpg

C:\Users\Shak\Documents\NetBeansProjects\CarRacing \nbproject\build-impl.xml:271: Compile failed; see the compiler error output for details.
BUILD FAILED (total time: 0 seconds)

At the end of the code you posted you have

car.setOnKeyPressed(e ->
 
        {
         switch ( e.getCode())
           {
             case UP:
                 animation.setRate( animation.getRate()+1);
                 break;
             case DOWN:
                 animation.setRate (animation.getRate()-1);
                 break;
 
         }};

Note how the "(" in the first line is not matched by any subsequent ")". This will give the sort of compiler errors you posted: ie ')' expected.

In general it is helpful if your compiler messages refer to some particular line - the first message is talking about line 118 of CarRacing.java - then it's a good idea to say which line of your code is being referred to. People tend to be lazy and won't count through the code you post to find it.

Im sorry am new to java and im not lazy i just dont know. So what is my problem if you dont mind answering? and how do i make Implement a new key handler for the HOME key.The home key will reset the baseX parameter to 0 so the car starts over at the initial position.its says create resetCarW() method in class

--- Update ---

and note that i was following direction on paper

I'm sorry about the misunderstanding: what I meant to suggest is that it is us (the people who are reading your post) who tend to be lazy. When you indicate which line is 118 or whatever, people will look at it, otherwise maybe not.

In any case, did you understand what I said about the mismatched parentheses?

Yea i undestood but direction tell me to car.setOnKeyPressed(e -> leave it like that.

Fair enough. But what happens if you insert the missing ')' just before the end of the statement? Note that the statement ends with the very final ';' character.

Those directions don't appear to be very good. Here's the correct structure (and preferred convention) of a lamda expression:

setOnKeyPressed(e -> {
 
});

Note where the start/end parenthesis and the start/end curly braces are.
