Learn Java Programming - FileWriter Tutorial

The purpose of the FileWriter class is to simply write character based files. The FileWriter class implements AutoClosable so we can use the try-with-resources type exception handling. There are five overloaded constructors in the FileWriter class, this tutorial will focus only the two that take a String parameter representing the file name. Regarding the other three constructors, I will revisit this class later once I have demonstrated the File and FileDescriptor classes. It also interesting to note that the FileWriter class does not define or override any public methods, so it inherits all of its methods from its superclass OutputStreamWriter; OutputStreamWriter is a subclass of Writer which is a subclass of Object and that describes the class hierarchy.
