Well if you re happy printing it in decimal  you could just make it positive by masking   int positive   bytes i   amp  0xff    If you re printing out a hash though  it would be more conventional to use hex  There are plenty of other questions on Stack Overflow addressing converting binary data to a hex string in Java
