 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 public static void convertMeters() { Scanner scan=new Scanner(System.in); echo ("ask and do stuff now"); } //Ask for a weight in pounds convert to kilograms. //it would say 180 pounds is 81.6466266 kilograms (convert by pounds*.453592 public static void convertToKilograms() { //You will need the following line in all methods in order to initialize the scanner. Scanner scan=new Scanner(System.in); echo ("ask and do stuff now"); } //Ask the user for their dogs name and age. You will then convert the dogs age in to years by multiplying by 7 and then saying: //Your dog Lassie is 42 yrs old. public static void findDogsAge() { //You will need the following line in all methods in order to initialize the scanner. Scanner scan=new Scanner(System.in); echo ("ask and do stuff now"); } //Ask the user for their first and last name and then they will say: //Jeff Borland, there are 4 letters in your first name and 7 in your last. public static void findLettersInName() { //You will need the following line in all methods in order to initialize the scanner. Scanner scan=new Scanner(System.in); echo ("ask and do stuff now"); } //Ask the user for 2 numbers and spit out the average public static void findAvg() { //You will need the following line in all methods in order to initialize the scanner. Scanner scan=new Scanner(System.in); echo ("ask and do stuff now"); } //Ask the user for their height in feet and inches (read both things seperately). // Then spit out You are 75 inches tall. public static void findHeight() { //You will need the following line in all methods in order to initialize the scanner Scanner scan=new Scanner(System.in); echo ("ask and do stuff now"); } /**************************************************************************/ //Advanced Students - do __ of below (look at notes on if statements, loops) //Ask the user for a number of miles for a taxi ride and then ask for // cost per mile and pickup cost. //Then spit out total charge (which is #of miles *cost per mile + pickup cost public static void findTaxiCost() { } //This will ask the user for the speed he was going and then spit out //the cost of a ticket (from 0-65 - \$0, 66-74 - \$85, 75-100 - \$200 101+ - \$1000 public static void findTicket() { } //This will find out the number of people who attended each block of the day //Ask the user 4 times (for each block) how many people attended //Then spit out the total //you must use a for loop public static void find4BlockTotal() { } //This will ask the user how many games they played, then it will find the winning percent //So the user might say 3, and the program will ask them 3 times if they won //So they might say y,n,n and then it will spit out you won 33.3% of the time public static void findWinningPrct() { } //create a method that will keep asking for a grade until the user hits -1. They will then //find the average of those grades // you will need to use loops public static void findAverage() { } //The following 2 are just for printing faster public static void echo (String x){ System.out.println(x); } public static void echo (int x){ System.out.println(x); } } ``` Advanced Students -notes on if statements, loops)
