Question

3. Write a java class named FinalyourLastName, which contains three methods: main, arrayMystery, and countTotalOdd. You need to create main method. Inside the main method...you need to create an integer array named myld that consists of each of the digits in your student ID, call arrayMystery method and print out myld, then call count TotaOdd method and print out the total number of odd digits in your ID. (8 points) The arrayMystery method is given as the following: You need to add comments about what each line is doing (4 points) public static void array Mystery (int[] a) { for (int i = 1; i <a.length - 1; i++) { ali] = a[i-1] - a[i] + a[i+1]; You need to create count TotalOdd method: the input of the method is a student ID as an integer array, the return is the total number of odd digits in student ID. (8 points)

Answer 1

public class FinalVhora {
   public static void main(String[] args) {
       int myID[]= {1,2,3,1,5,5,0,6};
       arrayMystery(myID);
       System.out.println("Number of Odd digits in Id: "+countTotalOdd(myID));
   }
   public static void arrayMystery(int []a) {
       // here we iterating through the array a
       // at each position we are adding the current element + nextelement - previous element
       // ex: 1,2,3 if we are 2 than it will 1-2+3=4 so now will be changed as 4
       for(int i=1;i<a.length-1;i++) {
           a[i]=a[i-1] -a[i]+a[i+1];
       }
   }
   public static int countTotalOdd(int []a) {
       int count=0;
       for(int i=0;i<a.length;i++) {
           if(a[i]%2==1)
               count++;
       }
       return count;
   }
}

console u <terminated > Finalhora [Java Application) C:\Program Files\Java Number of Odd digits in Id: 2
