WebAn int is 4 bytes (32 bits), a double is 8 bytes (64 bits) so the total is 12 bytes. The value of the number does not affect how many bytes are written. An int is 32 bits, regardless of its … 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.
