Question

Can someone help me turn this into an array below. And redo the display for the output below as well.

I don't want to use ArrayList. AREAS IN BOLD IS WHERE I DONT WANT TO USE ARRAYLIST

Here is the 2 classes.

import java.io.*;
import java.util.*;

class RainFall{

   private double[] data;

   public RainFall (double[] array){
       data = new double[array.length];
       for (int i = 0; i            data[i] = array[i];
   }
   public double totalRainFall(){
      double sum = 0;
      for (int i = 0; i           sum = sum + data[i];
      return sum;
   }
   public double average(){
      double sum = 0;
      for (int i = 0; i           sum = sum + data[i];
      return sum/data.length;
   }
   public int mostRain(){
      double max = 0;
      int index = 0;
      for (int i = 0; i           if (data[i] > max){
             max = data[i];
             index = i;
          }
      return index;
   }
   public int leastRain(){
      double min = 100;
      int index = 0;
      for (int i = 0; i           if (data[i] < min){
             min = data[i];
             index = i;
          }
      return index;
   }
   public ArrayList monthsHigherThanAverage(){
       ArrayList list = new ArrayList();
       double avg = average();
       for (int i = 0; i            if (data[i] > avg){
              list.add(i);
           }
       }
       return list;
   }
   double getValue(int a){
       return data[a];
   }
   String getName(int a){

       String res = "";
       switch(a){
          case 1 : res = "January";
                   break;
          case 2 : res = "February";
                   break;
          case 3 : res = "March";
                   break;
          case 4 : res = "April";
                   break;
          case 5 : res = "May";
                   break;
          case 6 : res = "June";
                   break;
          case 7 : res = "July";
                   break;
          case 8 : res = "August";
                   break;
          case 9 : res = "September";
                   break;
          case 10 : res = "October";
                   break;
          case 11 : res = "November";
                   break;
          case 12 : res = "December";
                   break;
       }
       return res;   
   }
  
}

public class DemoRainFall{

         double[] data1 = new double[12];

         try {
              FileInputStream fin = new FileInputStream("input.txt");
              Scanner sc = new Scanner(fin);
              for (int i = 0; i<12; i++){
                  data1[i] = sc.nextDouble();
              }
         }
         catch(Exception e){
             e.printStackTrace();
         }
         RainFall r1 = new RainFall(data);
         RainFall r2 = new RainFall(data1);

         System.out.printf("The total rainfall for this year : %.1f ",r1.totalRainFall());
         System.out.printf("The average rainfall for this year : %.1f ",r1.average());
         System.out.printf("The average rainfall for this year : %.1f ",r1.average());
         System.out.printf("The month with the highest amount of rain is %s with %.1f inches ", r1.getName(r1.mostRain()), r1.getValue(r1.mostRain()));
         ArrayList num = r1.monthsHigherThanAverage();
         System.out.println("There are " + num.size() + " months whose rainfall is higher than average:");
         for (int i = 0; i               System.out.printf("%s %.1f ",r1.getName(num.get(i)), r1.getValue(num.get(i)));
         }
         System.out.printf("The total rainfall for this year : %.1f ",r2.totalRainFall());

         System.out.println("There are " + num.size() + " months whose rainfall is higher than average:");
         for (int i = 0; i               System.out.printf("%s %.1f ",r2.getName(num.get(i)), r2.getValue(num.get(i)));
         }
    }
}

Explanation / Answer

class RainFall{ private double[] data; public RainFall (double[] array){ data = new double[array.length]; for (int i = 0; i
