16. differents between PrintWriter and PrintStream coderanch.com
The principal difference between using the ...Stream classes and the ...Reader/...Writer classes is that the former deal with raw bytes, while the latter deal with characters. Dealing with characters requires that specific "character encoding" be specified; Unicode in its various shapes (UTF-8, UTF-16, ...) is one such encoding. If you looks at the javadocs for PrintStream.print you'll see that it uses ...

public class PrintStream extends FilterOutputStream A PrintStream adds functionality to another output stream, namely the ability to print representations of various data values conveniently. Two other features are provided as well. Unlike other output streams, a PrintStream never throws an IOException; instead, exceptional situations merely set an internal flag that can be tested via the checkError method. Optionally, a PrintStream can ...

Single quotes (like this: 'c' ) in Java do not mean a String -- they mean a character constant. The type of a character constant is char, and char is just an unsigned 16-bit integer. '\n' is a special character constant that stands for the newline character; the Unicode value is 10 . You can always assign a narrower integral value ...
