Design a class FileArray that has a static method named writeArray. The method should take two arguments: the name of a file and a reference to an int array. The file should be opened as a binary file, the contents of the array should be written to the file, and then the file should be closed. Write a second static method in the class FileArray named readArray. The method should take two arguments: the name of a file and a reference to an int array. The file should be opened, data should be read from the file and written into the array, and then the file should be closed. FileArrayDemoDemonstrate both methods in a class called FileArrayDemo with the main method. Import both java. io.* and java. util.*;Creates a Scanner. Set a flag to false. while flag is falseUnder a try-catch-finally:Under try:Requests, and reads in the size of an int array called inputNumbers. It then creates the array and requests and reads in the values of the array. It also creates an output array of the same size called outputNumbers. Also request and read in the name of an output file of type .dat. It then creates the array and requests and reads in the values of the array. Call writeArray with references to the outputfile name and the array inputNumbers. Call readArray with references to the outputfile name and the array outputNumbers. Test for the various error conditions. Print out the output file. Set flag to trueUnder catch:Catch any InputMismatchException and print the trace (see output). – In this case set the flag to trueCatch and print the trace (see output).Catch and print the trace (see output).Catch any IOException and print the trace (see output).Under finally:Print "Program Completed"Sample Inputs/OutputsPlease enter the number of integers to enter:8.2InputMismatchjava. util.
