I have been working on these for so long. Please help. I am taking 5+ hours today, and 3+ yesterday. It is starting to click but this is just stumping me. Ive tried adding arrays to the emoticon class, someone in reddit suggested something to check if an array has been clicked? I know the solution cannot be that detailed as we have not gotten far in the text, please please please help!! thank you!!

The arrays do not go into the Emoticon class. The String values, for each Emoticon object, from the elements of the arrays, are passed to the Emoticon class as each Emoticon object is being created from within your subclass of World. Are you learning loops, per chance? or learning how to work with arrays? No matter. Either way you should refer to Variables - Arrays for arrays and Control Flow Statements - The for statement for the 'for' loop.

Yes, we have just learned loops. I just cannot think of how to do this. Why wont putting in 
Greenfoot.playSound(sounds[])
work?

Why wont putting in (...) work?
Because the playSound method requires a String, not a String array. Putting it another way, you are saying "play this sound" but then providing a whole bunch of sounds.
I just cannot think of how to do this.
As danpost says, the arrays do not go into the Emoticon class. Where are you actually creating the Emoticon instances (ie where do you have "new Emoticon( ... )")? show us the code in that class.

I have that in my HomeworkWorld class. I believe this is the code you are referencing to? If you would like, I can post the entire HomeworkWorld class 
for(int i=0; i<5; i++) {
        images[i]=new String("smiley"+(i+1)+".png");
        sounds[i]=new String("sound"+(i+1)+".wav");
        addObject(new Emoticon(images[i], sound[i]), 70*(i+1),50);
    }

Line 3 is changing the String values in the 'sounds' array to "sound1.wav", "sound2.wav", etc. instead of "hello.wav", "happy.wav", etc. Obviously "sound1.wav", et. al., will not be found.

@Lboogie0208 -- please start a new discussion thread for your issue and use the 'code'tag below the input box to insert your code into your post. Having the ability to refer to line numbers would be a great help in being able to assist. NVM -- I see that you have started a new one.
