Thread: Question about ArrayList

I'm trying to make a sort of theoretical MP3 player for an assignment, using the ArrayList class

Basically, I have a "Song" class that defines attributes of songs, including Title, Artist, Duration, and most importantly, Filesize. I have to use an ArrayList to store the songs, but this music player has a size limit

My question is, how do I get the ArrayList to specify a capacity limit, and then check the 'filesize' variable when determining how full it is? I'm really only familiar with the trimToSize method, which isn't what I need. If the limit is 15, I don't want 15 song objects, I want it to fill up based on the object's 'filesize' attribute

I hope that made any sort of sense

I have to create an ArrayList that can hold Song objects. Each Song object has an attribute, fileSize, that says, well, how big the file is. This ArrayList can hold any number of songs, but only as long as the total fileSize of those songs doesn't exceed a certain amount (To be set by me, say 15)

I'm not sure how to get that to work
