Question

This file has a class declaring two different versions of the countContains() method. The methods you will be writing in CountContains each have two parameters: the first has/can access the elements to review and the second parameter, an Object named obj. The method count and return the number of times obj appears as an element in the data accessed using the first parameter. Remember that elements and obj can be null. While not required, a little thought may let you complete one of these methods with only a single line of code.
