You will have an abundance of buttons in no time with that code (overlaid on top of one another). Create buttons in the constructor -- not act. The act method should test for clicks. The connection between the two arrays is already set by index value (position in arrays). No double for loops are required here.

Change line 19 into an array of Actor objects. Initialize it to size of filename array. Populate the array with the buttons as you create them. You will be using: 
arrayName[i]  = getNewButton("BUTTON 0"+(i+1));
Then use a for loop in act to check for clicks on those actors.

# 
Actor[] numButton = new Actor[4];
    numButton[0] = "BUTTON 01";
    numButton[1] = "BUTTON 02";
    numButton[2] = "BUTTON 03";
    numButton[3] = "BUTTON 04";
    numButton[4] = "BUTTON 05";
I changed the line 19 to this it says ']' expected as an error

Hello I would like more information about the index counter about the last time and by the way i would also like to know about a piece of code not sure I can do this with File Thank you for your help

File class not required by you. Use GreenfootSound class.

You will need a GreenfootSound field -- not an int field. It is required for the currently playing song so you can stop it before starting a different one.

I use the GreenfootSound class instead of the File class I don't see how to do it I find that the greenfoot API is quite limited compared to the java API

You can add an int array for total frames per song (loaded with proper values, of course).
