FileWriter Creates a Writer class that can write files. Its most commonly used constructor is as follows:
FileWriter (String FilePath)
FileWriter (String Filepath, Boolean Append)
Filewriter (File fileobj)
They can trigger ioException or securityException. Here, FILEPATH is a full path to the file, and fileobj is a File object that describes the file. If append is true, the output is attached to the file. The creation of the FileWriter class is not dependent on the file or not. Before creating a file, FileWrit is turned on when you create an object as an output. If you try to open a read-only file, it will trigger an ioException exception.
