Constructor Detail

BufferedRandomAccessFile

public BufferedRandomAccessFile(String filename,
                                String mode,
                                int bufsize)
                         throws FileNotFoundException

Creates a new instance of the BufferedRandomAccessFile.

Parameters:

filename - The path of the file to open.

mode - Specifies the mode to use ("r", "rw", etc.) See the BufferedLineReader documentation for more information.

bufsize - The buffer size (in bytes) to use.

Throws:

FileNotFoundException - If the mode is "r" but the given string does not denote an existing regular file, or if the mode begins with "rw" but the given string does not denote an existing, writable regular file and a new regular file of that name cannot be created, or if some other error occurs while opening or creating the file.

BufferedRandomAccessFile

public BufferedRandomAccessFile(File file,
                                String mode,
                                int bufsize)
                         throws FileNotFoundException

Creates a new instance of the BufferedRandomAccessFile.

Parameters:

file - The file to open.

mode - Specifies the mode to use ("r", "rw", etc.) See the BufferedLineReader documentation for more information.

bufsize - The buffer size (in bytes) to use.

Throws:

FileNotFoundException - If the mode is "r" but the given file path does not denote an existing regular file, or if the mode begins with "rw" but the given file path does not denote an existing, writable regular file and a new regular file of that name cannot be created, or if some other error occurs while opening or creating the file.
