		// First we need to initialize the classes we need. In this class we only need the Scanner class to get input from the console.
		
		Scanner input = new Scanner(System.in); //This statement initializes the Scanner class and sets it up to recieve input from the console.
		
		// This is where you get the data you need to work with, with a simple console prompt and retriving input to a String variable.
		
		System.out.print("Please input your location in the format 'City, State Zip':"); //This prints a statement prompting you for your location.
		String location = input.nextLine(); //This retrives the next line you type into the console and stores it into a new String variable.
		
		// Ok, it's time to get into the nitty gritty String processing. Hold on to your seats and ask me for any questions you have!
		
		int comma = location.indexOf(","); //Finds the location of the first comma and stores the location in a variable. This will be important for the next thing.
		String stateAndZip = location.substring(comma + 2, location.length()); //This cuts out everything before the first space for easier String processing.
																																					//The +1 in the comma is essential because we want to start retrieving
																																					//at the first character of the state instead of at the comma before the state!
																																					//If we used the location of the first space, it would break when we put in locations
																																					//with more than one space in the name.
		int secondSpace = stateAndZip.indexOf(" "); //Gets the location of the second space in the original string, but in relation to the stateAndZip variable we made.
																								//That means that the number in the secondSpace variable is the location of the first space in the stateAndZip
																								//variable, a.k.a. the space between the state and zip code!
		
		// Now it's time to actually get the stuff that the lab wants you to get!
		
		String city = location.substring(0, comma); //This substring method gets the section of the inputted string that contains the city.
																								//It basically slices the string into the part from the beginning to the location of the comma.
																								//0 is where the string starts, and comma indicates that we want the String up until the location of the comma.
		System.out.println("City:\t" + city); //Print out the first thing the lab wants you to get: the city!
		
		String state = stateAndZip.substring(0, secondSpace); //This substring method gets the section of the stateAndZip string we created that contains the state.
																													//It works because when we initialized the secondSpace method, we got the location of the second space	
																													//of the entered string but using the stateAndZip string so it will work with the stateAndZip variable.
		System.out.println("State:\t" + state); //Print out the second thing the lab wants you to get: the state!
		
		String zipCode = stateAndZip.substring(secondSpace + 1, stateAndZip.length()); //This substring method gets the last thing we need. The zipCode! 
																																									//It basically uses the location of the space between the state and zip code,
																																									//and goes one after it to the beginning of the zip code, then slices that part out.
		System.out.println("Zip:\t" + zipCode); //Print out the last thing we need: the zip code! We're done! \
