Replace String in byte[]

Welcome,
I have a byte[] which is the binary representation of a String. And I wanted to replace a part of this String and get back the new byte[]!
I have tried:

String string = new String(array);
string = string.replace("#+#","SOME STRING");
array = string.getBytes();

The problem is that array is that the array afterwards is something different and not only because of the replacement.
The content of the array are serialized objects seperated with "#+#".

Be explicit about the character encoding you are using and use an encoding such as "Latin-1" where all byte sequences map to valid Unicode characters:

String string = new String(array, "Latin-1");
string = string.replace("#+#","SOME STRING");
array = string.getBytes("Latin-1");
