5. Change Account Validation Modification: [[[[[[[JAVA]]]]]]

Modify the program you wrote for programming challenge 4 (change account validation) so it performs a binary search to locate valid account numbers. use your choice of sorting algorithm to sort the array before the binary search is performed.

This is question 4's info:

Create a class with a method that accepts a change account number and its argument. the method should determine whether the number is valid by comparing it to the following list of valid change account numbers:

5658845,4520125,7895122,8777541,8451277,1302850, 8080152,4562555,5552012,5050552,7825877,1250255, 1005231,6545231,3852085,7576651,7881200,4581002

These numbers should be stored in an array, us a sequential search to locate the number passed as an argument. if the number is in the array, the method should return true, indicating the number is valid.

I am mainly looking for the answer to 5, do not need 4.
