I have a String that I want to decode to a binary object (BigInteger or its String) Say for instance I got the String An now I want to decode it using the Base64.getDecoder() method, such as: According to that, the value of result is 101101001100010011000000110001001100000011000000110001001100010011000000110001001100010011000100110000 which does not match with the result that I obtain using any online decoder:

Java Base64 encoding loss of data
say I have the following snippet, where certificate is a java Certificate object: Is there any chance data will not be equal to newData? basically, is there loss of information to string and then back? Thanks Answer Assuming nothing explodes due to out-of-memory errors or similar general problems, this code should be fine, with one big exception: You are transforming

SonarCloud code smell when I convert byte[] to String with String constructor
This is my function that decodes a JWT Object to String: SonarCloud detect a code smell when I convert base64Url.decode(base64EncodedBody), that is a byte[], on a String. This is the issue: Constructors should not be used to instantiate “String”, “BigInteger”, “BigDecimal” and primitive-wrapper classes. Constructors for String, BigInteger, BigDecimal and the objects used to wrap primitives should never be used.
