WebA primitive int obviously takes 4 byte. An Integer object has an overhead of about 24 byte (this is implementation specific) plus 4 byte for the data, so about 28 byte. An array is an object which also has an overhead of 24 bytes plus 4 bytes for the length plus data. An int [] array thus uses 28 bytes plus 4 bytes for each int.
