A PrintStream can also be created to flush the output automatically.
For example, the following command run the program with default charset of UTF The PrintWriter class should be used in situations that require writing characters rather than bytes. File class maintains these system-dependent properties, for you to write programs that are portable: Directory Separator: in static fields File.
That would add another library for the reader to understand that has nothing to do with reading files in Java. If none of these options is specified, the channel is opened for reading.
In a single atomic operation, the createFile method checks for the existence of the file and creates that file with the specified attributes, which makes the process more secure against malicious code.
A SeekableByteChannel also supports truncating the file associated with the channel and querying the file for its size. Removing the encoding from this code will simply cause the system's default encoding to be used instead.
