No, the disk file is a text file and contains only characters.
FileWriter
Here is a list of some of the constructors and methods
used with FileWriter
.
All of the methods are inherited from its ancestors.
For a complete list of methods look at the
Java documentation
on the Web.
When you write()
characters to a file,
you are asking the operating system to write to the disk.
But the operating system might not do the work until later
depending on how busy it is.
The flush()
method ensures that all data is actually sent to the disk.
Constructors
FileWriter(String fileName) An IOException is thrown if the file cannot be created. FileWriter(String fileName, boolean append) An IOException is thrown if the file cannot be opened for appending.
Methods
public void close() throws IOException Flush the stream and close the file. public void flush() throws IOException Flush the stream. public void write(String str) throws IOException Write a string.
Why not do a flush()
after each write()
to be
sure that all the data is written to the disk?
