Java Integer toHexString() Method

The toHexString() method of Java Integer class returns a string representation of the integer argument as an unsigned integer in hexadecimal base 16.

The following characters are used as hexadecimal digits:

Note: If the argument is negative, the unsigned integer value is the argument plus 232 otherwise, it is equal to the argument. This value is converted to a string of ASCII digits in hexadecimal (base 16) with no extra leading 0s. If the unsigned magnitude is zero, it is represented by a single zero character '0' otherwise, the first character representation of the unsigned magnitude will not be the zero character.
