Array: Eliminate duplicates

  
package Ch7;

/*
    Q: Write a method that returns a new array by eliminating the duplicate values
       in the array using the following method header:
       public static int[] eliminateDuplicates(int[] list)
       Write a test program that reads in 10 integers, invokes the method, and displays
       the distinct numbers separated by exactly one space.
