If the iodata. dat file does not exist, what will happen when the following statement is executed? randomaccessfile randomfile = new randomaccessfile("iodata. dat", "rw");

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.
