new File(\"abc.txt\") does not create actual file while new FileWriter(\"abc.txt\") creates a file on disk. While going through source code i found

Answer 1

There are lots of reasons really, but:

File is used by many classes in java.io. FileReader, etc... FileWriter is a "convenience" class that uses File and it enables the programmer to be more productive. Some Classes just want a File object which points to a file location and then they operate on it as needed to support their processing. Other Classes might support a FileWriter because it will only be writing to a file and not reading. It also makes the API more strongly-typed.
