Question

***** JAVA ONLY *****

Write a program that uses nested loops to collect data and calculate the average rainfall over a period of years. Frist the program should ask for the number of years. The outer loop will iterate once for each year. The inner loop will iterate 12 times, once for each month. Each iteration of the inner loop will ask the user for the inches of rainfall for that month. After all iterations, the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.

***** Do not accept a number less than 1 for the number of years. Do not accept negative numbers for the monthly rainfall. *****

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

import java.util.*;
import java.io.*;
import java.text.DecimalFormat;
public class Rainavg{
public static void main(String[] args)   
{
Scanner kb=new Scanner(System.in);   
int years,month=12;
double total=0,average;   
int months[];
String input;

months = new int[12];
DecimalFormat df = new DecimalFormat("##0.00");
System.out.println("Input how many years you want to calculate for ");
input = kb.nextLine();

for (int y = 1; y <= Integer.parseInt(input); y++)
{   
System.out.println("Rainfall amount for year #"+y+":");
years = Integer.parseInt(input);
while (y < 1)
{
System.out.println("Error! Less than 1");
}
for(int m = 1; m<=12; m++ )
{   
System.out.println("Rainfall amout for month #" + m + ":");

months[m-1]= kb.nextInt();
while (m < 0)
{
System.out.println("Error! Less than 1");   
}
}

for(int i=0; i<12;i++)
{
total= total+months[i];
}   

System.out.println("Total rainfall amount for year " + y + " is " + total);
average = total/12;
System.out.println("Average rainfall int the year " + y + " is " + average);

}
}

}

Kindly revert for any queries

Thanks.
