string to hex value

Question

Is there any java utility to convert string to hex value (integer) ?

Answer 1

Your question is a little ambiguous, I think.

If you have a hex string (e.g. "ab10"), then you can use

int i = Integer.valueOf(s, 16).intValue();

Answer 2

When you have a string starting with 0x or #

Integer.decode(hexStr);

is the goal

Or

Integer.parseInt(hexString, 16);

Answer 3

Is this what you are looking for?

Integer.toHexString(Integer.parseInt(String));

Answer 4

Try some of the methods of the Integer class:

Integer.toHexString(Integer.parseInt(myString, 10))

This assumes that your original string is an integer base ten.
