Different computers use binary instructions:
For integer, there are four kinds of representation:
> Binary: 0, 1, 2 into a full, or start with a 0b in JAVA 0B
> Decimal: 0-9, into the full 10 1
> Octal: 0-7, 8 into a full, expressed in numbers begin with 0
> Hex: 0-9 grade AF, over 16 into the 1. He expressed with 0x or 0X. AF case insensitive here: As 0x21AF + 1 = 0X21B0
class BinaryTest{
public static void main(String[] args){
