How to Convert Byte to String

Convert bytes to a string

Decode the bytes object to produce a string:

>>> b"abcde".decode("utf-8") 
'abcde'

The above example assumes that the bytes object is in UTF-8, because it is a common encoding. However, you should use the encoding your data is actually in!

How to convert byte array to string and vice versa?

Your byte array must have some encoding. The encoding cannot be ASCII if you've got negative values. Once you figure that out, you can convert a set of bytes to a String using:

byte[] bytes = {...}
String str = new String(bytes, StandardCharsets.UTF_8); // for UTF-8 encoding

There are a bunch of encodings you can use, look at the supported encodings in the Oracle javadocs.

convert a byte array to string

You could convert the byte array to a char array, and then construct a string from that

scala> val bytes = Array[Byte]('a','b','c','d')
bytes: Array[Byte] = Array(97, 98, 99, 100)

scala> (bytes.map(_.toChar)).mkString 
res10: String = abcd

Converting Byte to String and Back Properly in Python3?

Note: Some codes found on the Internet.

You could try to convert it to hex format. Then it is easy to convert it back to byte format.

Sample code to convert bytes to string:

hex_str = rnd_bytes.hex()

Here is how 'hex_str' looks like:

'771296b8'

And code for converting it back to bytes:

new_rnd_bytes = bytes.fromhex(hex_str)

The result is:

b'w\x12\x96\xb8'

For processing you can use:

readable_str = ''.join(chr(int(hex_str[i:i+2], 16)) for i in range(0, len(hex_str), 2))

But newer try to encode readable string, here is how readable string looks like:

'w\x12\x96¸'

After processing readable string convert it back to hex format before converting it back to bytes string like:

hex_str = ''.join([str(hex(ord(i)))[2:4] for i in readable_str])

How to convert byte array to string

Depending on the encoding you wish to use:

var str = System.Text.Encoding.Default.GetString(result);

How to convert UTF-8 byte[] to string

string result = System.Text.Encoding.UTF8.GetString(byteArray);

Converting byte array to String Java

Try something like this:

String s = new String(bytes);
s = s.replace("\0", "")

It's also posible, that the string will end after the first '\0' received, if thats the case, first iterate through the array and replace '\0' with something like '\n' and do this:

String s = new String(bytes);
s = s.replace("\n", "")

EDIT:
use this for a BYTE-ARRAY:

String s = new String(bytes, StandardCharsets.UTF_8);

use this for a CHAR:

String s = new String(bytes);

How do I convert a Python 3 byte-string variable into a regular string?

You had it nearly right in the last line. You want

str(bytes_string, 'utf-8')

because the type of bytes_string is bytes, the same as the type of b'abc'.
