  5. In this tutorial we will learn how to append content to a file in Java. There are two ways to append: 1) Using FileWriter and BufferedWriter: In this approach we will be having the content in one of more Strings and we will be appending those Strings to the file.The file can be appended using FileWriter alone however using BufferedWriter improves the performance as it maintains a buffer

This might sound flippant, but PrintStream prints to an OutputStream, and PrintWriter prints to a Writer.Ok, I doubt I'll get any points for stating the obvious. But there's more. So, what is the difference between an OutputStream and a Writer? Both are streams, with the primary difference being a OutputStream is a stream of bytes while a Writer is a stream of characters Using PrintWriter. Java's PrintWriter class extends the Writer class. It prints the formatted representation of objects to the text-output stream. We'll perform a simple test. Let's create a PrintWriter instance pointing to an existing file, deleting existing content of the file by just closing it, and then make sure the file length is empty: new PrintWriter(FILE_PATH).close(); assertEquals(0.
