My Scala code received a binary from byte stream,it looks like [61 62 63 64].The content is "abcd". I use toString to convert it p, but failed. How do I print it as string ?
You can always convert the byte array to a string if you know its charset,
val str = new String(bytes, StandardCharsets.UTF_8)
And the default Charset
would used if you don't specify any.
