Increase Hex (JAVA)

Question

can you increase the hex value in java? that is, "hexadecimal value" = "hexadecimal value" ++

Answer 1

It depends on how the hex value is stored. If you have a hexadecimal value in a string, convert it to Integer, increase and convert it.

int value = Integer.parseInt(hex, 16);
value++;
String incHex = Integer.toHexString(value);

What does "hexadecimal value" mean? What type of data is your value stored in?

Note that int / short / char / ... doesn't care how your value was originally represented:

int i1 = 0x10;
int i2 = 16;

i1 i2 . Java ( ) /.
