title: method created array to saved array
body: <p>Im making a game thingamajig, which uses a large array (int[][]) as a map. I need to be able to take in different maps, and i have the code that goes map from a file -> array, but this is a method. is there a neat way to save this array and be able to access the data quickly without having to run the file-> array method every time?</p>
