What's the best and fastest way to convert a byte array to a String.
The (toString doesn't work, it gives strange characters).

I prefere a way that uses a loop that loops in the bytes of the array
and convert them to characters then append them to a string.

Thanks.

How about one of the variants of this, which allows you to specify a
character set encoding?

a.lang.String)

That URL was supposed to take you to this String constructor:

public String(byte[] bytes, String charsetName)
throws UnsupportedEncodingException

The charsetName tells the constructor how to interpret the bytes in the byte
array -- they could be UTF-8, ASCII, EBCDIC, or Swahili, which explains the
strange characters you get from toString, which just uses the default
encoding for your platform.
