Solution: Hello world

- So how did you make out?…I hope you are able to compile and run your program…from the command line.…It's pretty cool, right?…Let's take a look at my solution.…Remember that your solution might be very different.…All programmers program a little bit differently.…We'll start with the code.…At the very top I had to remember…to import my Java.util.scanner.…Line two is where I can declare my class, name and age.…Line three I have my public static void main,…then I read in the value that the user entered…as the command line argument…into the variable called prompt.…

I use that value to print…that back out to the screen.…I know the users going to type in a string and an integer.…So I create a string for the name…and an integer for the age.…On line nine I create my new scanner object.…Scanner in = new Scanner (System.in).…Then I read in the name = in.nextLine…and I read in the age = in.nextInt.…I don't have to parse it since this is not coming…from the command line prompt.…This is actually inside the running program…and then I print out whatever the user entered.…
