  • byte uses 1 byte while int uses 4 bytes.
  • integer literals like "45" are of int not byte.If you want a literal to be a byte, you have to cast it: "(byte)45".
  • When values are promoted as part of an expression or as parameters to a method call, they may be promoted to int, but never to byte.
  • Many parts of the Java language used int, but none of them use byte. For example, the length of an array is an int.
