Write two methods that read data from the console and store the data in an array:

a. The method:     

                      int readData(int [ ] x)

reads a list of at most 100 integers into the array x. A sentinel 999 terminates the list. The method returns the size of the list.

Largest and Smallest

Design a method that determines the largest and smallest values stored in an integer array, x. Your method should return these values in an array of length two. Use the following algorithm:

Initialize variables currentBig and currentSmall to the larger and smaller values of x[0] and x[1]. Process the rest of the list, two elements at a time. Compare the larger of the two elements to currentBig , and replace currentBig if necessary.

Compare the smaller of the two elements to currentSmall, and replace currentSmall if necessary. Test your method in a program and include a method that reads a list, terminated by 999, into an array.
