Hexadecimal string value to 0x Byte

Question

How do I convert string value of a hexadecimal to be used as a byte. For example, I get the hexadecimal string value through -

 String strVal = String.format("%02x", buf[i]); //lets say it is "3D"

Now I want to convert that into a byte, so I can do something like this

byte bVal =  0x[value?] //0x3D;

Thanks

Have you looked into commons-codec? That'll take care of it for you. — Dan, Apr 20 '15 at 15:03

String hex = ...;
int temp = Integer.parseInt(hex , 16);

byte result = (byte) temp;

You can use getBytes().So strVal.getBytes().
