Java 2 8 10 16

An integer literal is expressed in decimal (base), hexadecimal (base), octal (base 8) , or binary (base 2).

int decimal = ten;         int hexadecimal = 0x10;         int octal = 010;         = "Ten";        System.out.println (decimal);                        // Ten        SYSTEM.OUT.PRINTLN (hexadecimal);                  //  -        System.out.println (octal);                       // 8        // 2

Hex starts with 0x

Octal starts with 0

No binary numbers

Values are represented in 10 binary

How hexadecimal numbers are read

0 1 2 3 4 5 6 7 8 9 A B C D E F

Sample 1

0X10 read as a zero fork 10, can not be read as a zero fork 10 (decimal notation can not be applied to hexadecimal causes confusion); cannot be read as a zero Fork 16 (16 is its corresponding 10 binary value)

Sample 2

16 binary 11 means decimal is 17.

A hexadecimal representation of a decimal is 17.

The easy-to-understand system is decimal, which is used in decimal notation.
