Creates the file with the given file name.

Explanation:

Here, the constructor is RandomAccessFile randomFile = new RandomAccessFile ("IOData. dat", "rw"); The general form to construct the object of RandomAccessFile class is RandomAccessFile randomFile = new RandomAccessFile (String Filename, String mode); Here, the String Filename is the filename of the file that has to executed with the String mode. The modes decide the accessibility of the file, types like r - 'read only' the file, rw - 'read and write' the file. If the file doesn't exists it creates the file with the given filename. If a file with read only mode is tried to write in the file, then it throws exceptions.
