Which array takes up more memory in the heap after these three lines are run by the JVM? Array 1: Integer[][] x = new int[10][]; Array 2: String[] y = new String[10]; Array 3: int[][0] z = new int[10][0]; Array 3 is an array of arrays of arrays and so it occupies more memory in the heap. O Array 1 and Array 3 will both occupy the most amount of memory in the heap. Array 3 is an array of arrays of arrays of ints (which are primitive) and Array 1 is an array of arrays of Integers (objects). An array of arrays of ints will occupy the same memory as an array of Integers. All three arrays occupy the same amount of memory in the heap since all arrays have the same length and each store references to objects which are the same size regardless of the kind of object.
