Make a class that represents a file. This class will have the ability to calculate the number of lines in that file and the ability to search through the file. The getNumMatchingWords method will take a bit of text and determine how many lines contain that text. Make the comparison not care about case. Example: if the user is searching for hello and a line contains the text hello hello hello then this counts as one. Use the contains method defined on Strings to help with this.     Fields - filename : String Methods + FileStats(filename : String) + getNumMatchingWords(key : String) : int + getNumLines() : int   Use test case 1 as result
