The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once.
