It is possible that different amounts of memory will be allocated in different situations. However, the case that is both most interesting and most measurable is a large boolean[] array. I've previously measured it as one byte per element, rounded up to a multiple of 8 and plus 8 bytes per array overhead. However, your mileage may vary, and if you really need to know you should measure it on the system you care about. Patricia Patricia Shanahan |
