/** This program demonstrates a solution to the FileArray Class programming challenge. */

public class FileArrayDemo { public static void main(String[] args) { int[] numbers = {1, 2, 3, 4, 5, 6, 7, 8 }; int[] test = new int[8];

} }

Name the file with the two static methods FileArray.java. Modify the FileArrayDemo.java file to read in the numbers array to a binary file, then the file should be read to extract the data in the file and read it into the test array. Then printout the test array to the screen.

Design a class that has a static method named writeArray. The method should take two arguments: the name of a file and a refernce 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 method in the class 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 stored in the array, and then the file should be closed. Demonstrate both method in a program.
