Elfman · 2006-10-28 10:13:53

I'm currentl;y writting a program in java in which i have an event listener. Upon a certain event i want to add a value to an array. I haven't done much in java but coming from c++ arrays were easy declare and assign. Can anyone tell me how i should best go about this in java. I have looked into arraylist is this the way…

Java arrays are static in size at initialisation time. So to add to the array you need to create a new array and then copy that array.

Look into collections as a better solution.
