Question

Java

Create a class NumberList that stores a list of integers and a list of doubles. Create a driver class that creates two objects of type NumberList and and ask the user to fill one of these lists. The other list should have integer values 1,2,3,4 and double values 1.1, 2.2, 3.3, 4.4. Declare a winner between the two objects by comparing their integer lists element by element and counting which list has more winning positions (the lists will need to be the same length). Then sum the winning object's double list and declare this sum as its 'house total'. All operations should be performed with methods from the NumberList class.

Your output should be the winning object's list of integers on one line (e.g., '5 4 8 2'), the sum of its double list (e.g., '10.2') and some type of acknowledgement that that object one (e.g., "And the winner is ... ").

Answer 1

Points to consider:

1. Finding the array.
2. Then find the comparison.
3. Judge for the winner
4. Print

Code

import java.util.Scanner;

class NumberList{
   public int a[];
   public double b[];
   public NumberList(int a[], double b[]) {
       this.a = new int[4];
       this.b = new double[4];
       for(int i = 0;i<4;i++) {
           this.a[i] = a[i];
           this.b[i] = b[i];
       }
   }
}
public class Game {
   public static void main(String args[])
   {
       int a[] = new int[] {1,2,3,4};
       double b[] = new double[] {1.1,2.2,3.3,4.4};
       NumberList l1 = new NumberList(a, b) ;
       Scanner scan= new Scanner(System.in);
       System.out.println("Enter the list 4 integer values");
       for(int i = 0;i<4;i++) {
           a[i] = scan.nextInt();
       }
       System.out.println("Enter the list 4 double values");
       for(int i = 0;i<4;i++) {
           b[i] = scan.nextDouble()();
       }
       NumberList l2 = new NumberList(a, b);
       int winl1 = 0, winl2 = 0;
       for(int i = 0;i<4;i++) {
           if(l1.a[i] > l2.a[i]) {
               winl1 ++;
           }else {
               winl2 ++;
           }
           if(l1.b[i] > l2.b[i]) {
               winl1++;
           }else {
               winl2++;
           }
       }
       double sum = 0;
       if(winl1>winl2) {
           System.out.println("Winner list of integer: ");
          
           for(int i=0;i<4;i++) {
               System.out.print(l1.a[i] + " ");
               sum += l1.b[i];
           }
       }else {
           for(int i=0;i<4;i++) {
               System.out.print(l2.a[i] + " ");
               sum += l2.b[i];
           }
       }
       System.out.println("\n"+ sum);
       System.out.println("The winner is list: " + (winl1>winl2?"List 1":"List2"));
   }
}
