Answer:
No.
No.
Here are two (out of several) FileWriter constructors:
FileWriter(String fileName)
FileWriter(String fileName, boolean append)
The first constructor's argument fileName
is the name of a disk file that will be created in the
current subdirectory.
If there is already a file with that name,
it will be replaced.
Here is an excerpt from the example program.
The FileWriter constructor creates a
disk file, reaper.txt.
The constructor returns a reference to the FileWriter object
which is assigned to writer.
Now writer can be used to write to that file.
public static void main ( String[] args ) throws IOException
{
String fileName = "reaper.txt" ;
FileWriter writer = new FileWriter( fileName );
. . .
The second form of the constructor has
an argument, append.
If append is true,
the constructor
will open an existing file for writing
without destroying its contents.
If the file does not exist, it will be created.
