Convert from byte array to string and string to byte array in java [duplicate]

Answer 1

Use Base64.

Apache Commons Codec has a Base64 class which supports the following interface:

String str = Base64.encodeBase64String(bytes);
byte[] newBytes = Base64.decodeBase64(str);

Answer 2

Try a specific encoding:

String s = new String(A, "ISO-8859-1");

byte[] b = s.getBytes("ISO-8859-1");
