HWJ3 - Using the scanner class: (This counts as 9 points)

Start with the code below and use it to create the 9 methods described.

import java.util.Scanner;
public class HWJ3_Scanner
{
    public static void testOfScannerClass()
    {
        //You need to initialize the scanner in order to use it
        Scanner scan=new Scanner(System.in);
        //test of reading Strings
        System.out.println("Type in a string");
        String theString=scan.nextLine();
        echo("In case you forgot, you just typed " + theString);

        //test of reading int
        System.out.println("Type in an integer");
        int theInt=scan.nextInt();
        echo("In case you forgot, you just typed " + theInt);

        //test of reading double
        echo("Type in a decimal");
        double theDouble=scan.nextDouble();
        echo("In case you forgot, you just typed " + theDouble);
    }

    //Create a method that will ask your name and age and then
    // find how many years older mr borland is then you (im 40)
    //it will spit out Mr Borland is 22 yrs older than Luke
    public static void ageDiff()
    {
        Scanner scan=new Scanner(System.in);
        echo ("ask and do stuff now");
    }

    //Create a method that will convert meters to centimeters and also inches.
    //It will ask for meters and then print out the number of cms and inches (there are 39.37 inches in meter)
    //So if they put in 1.5 meters, it will say that is 150 cms or 59.06 inches

   }

    }

    //Ask the user for 2 numbers and spit out the average
