Java code To convert byte to Hexadecimal

Question

I have an array of bytes. I want each byte String of that array to be converted to its corresponding hexadecimal values.

Is there any function in Java to convert a b

Answer 1

If you are happy to use an external library, the org.apache.commons.codec.binary.Hex class has an encodeHex method which takes a byte[] and returns a char[]. This methods is MUCH faster than the format option, and encapsulates the details of the conversion. Also comes with a decodeHex method for the opposite conversion.
