Is there any function equivalent to php bin2hex() for Java?
I need to convert a binary to hexadecimal.

Answer 1

You can do it like this

String hexa = Integer.toString(Integer.parseInt("1111", 2), 16);

And hexadecimal to binary as well

String bin = Integer.toString(Integer.parseInt("ff", 16), 2);
