adding a null terminator to a java string

I am using a java program to send an xml string to socket being processed by a C program.
When reading the string it is looking for a \n to know the string is complete.
Is the simplest way to do this to add the \n to my java string?
String A = "<test>hello</test>";
String B = (StringA + "\n");

If it is looking for "\n" then this is indeed the best way to add it
String B = StringA + "\n";

End of line can be different on different systems
you can add end of line specific to the system on which you are writing the string in this way:
String B = StringA + System.getProperty("line.separator");

However what it is that your server part is waiting for is another question

If you add "\n" you'll be adding a newline character, not a null character. A null character would be something like '\0'

But probably your server will rather be looking for end of line then for null termination

You'll find that the System line separator almost certainly does end with \n anyway, in which case you can save yourself and the system the bother of appending \n by using a PrintWriter. Just as a precaution, you can place the following at the head of your app entry point:

        String sep = System.getProperty("line.separator");

        if (!sep.endsWith("\n")) {
            throw new RuntimeException(
                "System line separator not suitable for network app");
        }

Of all ways to implement it, that's not the best. Quite possibly it's the worst
