Question
Consider the following definition of a MysteryBox object:
public class MysteryBox {
private final int x0, x1, x2, x3;
private final double y0;
private final boolean z0;
private final long[] a = new long [248];
}
Using the 64-bit memory cost model from lecture, how many bytes does each object
of type MysteryBox consume? Include all memory referenced by the object (deep memory).
Answer
Your answer should be a positive integer that is a multiple of 8.
