What Java Equivalent method to Apache's Hex.encodeHexString() Method

Question

I use Java8 and I wonder if Java8 has an equivalent method to org.apache.commons.codec.Hex.encodeHexString

Thanks!

Answer 1

Integer.toHexString(int) is available. As is BigInteger.toString(int radix). Both can encode to hex.

Answer 2

It is hard to tell what you really need without seeing example of input and expected output, but based on your comment under @Elliott's answer:

Hex.encodeHexString() - input is a byte[] and output is String.

you may be looking for HexBinaryAdapter class and its

• String marshal(byte[] bytes)
• byte[] unmarshal(String s)

methods (although they are non-static so you will need instance of this adapter).

They internally invoke these static methods:

• DatatypeConverter.printHexBinary(bytes)
• DatatypeConverter.parseHexBinary(s)

So you may want to take a look at DatatypeConverter class.
