Hi,how would i create an array of images ,to display the random images from the neatbeans project folder ,by submitting the button and dispaly in the pane?

You can create an array in various ways .

String[] array = new String[]{"I","did","not","read","my","textbook","and","I","don't","know","what","a","Google","is","nor","have","I","studied","line","63","outside","of","the","Netbeans","GUI-builder"};

Furthermore, it seems that most of this code was given to you (or generated by Netbeans) and that you haven't done much of it yourself. Until then I will only leave you reading material for your other questions:
