Typecasting int to char, then search array
Use cast_number/*char*/ = (char) help_variable_remove_pv + '0'/*int*/; instead of cast_number/*char*/ = (char) help_variable_remove_pv/*int*/; A character and an integer somewhat are different. This means that '0'(character 0) and integer 0 aren't equal. You'll have to add 48 (ASCII value of '0') to 0 to get the integer value of '0'. See...
byte array to string and inverse : recoverded byte array is NOT match to original byte array in Java
You cannot convert an arbitrary sequence of bytes to String and expect the reverse conversion to work. You will need to use an encoding like Base64 to preserve an arbitrary sequence of bytes. (This is available from several places -- built into Java 8, and also available from Guava and...

Replace multiple numbers with other numbers in a string using REGEX c#
As you mentioned you need to capture and replace the max value, I will take into account only that non-capturing group. The special character \s+ is used to indicate one or more white spaces.

saving base64 decoded string into a zip file
Don't create a string from your byte array (String decodedString = new String(byteArray);), to then use an OutputStreamWriter to write the string, because then you are running the risk of introducing encoding issues that are platform dependent.
