A better question is why java byte type is not a range of 0..255? In fact many do ask this question, in most languages byte type is unsigned, but in java byte is signed too, and I (and many other) believe …

Apr 24, 2013 · I read this line in the Java tutorial: byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The …

The byte data type can be useful for saving memory in large arrays, where the memory savings actually matters. They can also be used in place of int where their limits help to clarify your code; the fact that …

A Java byte is a primitive with a minimum value of -128 and a maximum value of 127 (inclusive). 87 is within the allowed range. The byte data type can be useful for saving memory in large arrays, where …

Mar 3, 2013 · 2 I need to get the byte / 8 bit representation for numbers between 0 and 255. Is there any comfortable way to do this in Java? Seems like most methods are intended to be work with 4 byte …

Mar 31, 2022 · A byte in Java is an octet, 8-bits. This is true of both the byte primitive type and the Byte wrapper class. As a signed value, that means a range of -128 to 127. As an unsigned value, that …

The fact that primitives are signed in Java is irrelevant to how they're represented in memory / transit - a byte is merely 8 bits and whether you interpret that as a signed range or not is up to you. There is no …
