Stuck on this code...
 

Hello I am still very new to java and I've been looking over this code for quite some time. There are two hurdles I am trying to get by with which the later one actually just started happening recently... I am trying to post the largest and smallest index number from the last two methods. The second thing that is happening is that now my code just hangs after I input the rainfall numbers.... any help would be greatly appreciated!!

import java.util.Scanner;
import java.text.DecimalFormat;

public class Rainfall
{
public static void main(String[] args)
{
final int MONTHS = 12;
double[] rain = new double[MONTHS];
initRain(rain);
double total = totalRain(rain);
double average = averageRain(rain, total);
double most = mostRain(rain);
double least = leastRain(rain);
DecimalFormat digit = new DecimalFormat("#.0");
System.out.println("The total rainfall of the year is " + digit.format(total));
System.out.println("The average rainfall of the year is " + digit.format(average));
System.out.println("The month with the highest amount of rain is " + most);
System.out.println("The month with the lowest amount of rain is " + least);
}
public static void initRain(double[] array)
{
Scanner keyboard = new Scanner(System.in);
for (int x = 0; x < array.length; x++)
{
System.out.print("Enter Rainfall for month " + (x + 1) + ": ");
array[x] = keyboard.nextDouble();
}
}
public static double totalRain(double[] array)
{
double total = 0;
for (int x = 0; x < 12; x++)
total += array[x];
return total;
}
public static double averageRain(double[] array, double total)
{
return total / array.length;
}
public static double mostRain(double[] array)
{;
double maximum = array[1];
int value = 0;
for (int i=0; i < 12; i = i++)
{
if (array[i] >= maximum)
maximum = array[i];
value = i;
}
return value;
}
public static double leastRain(double[] array)
{
double minimum = array[0];
int value;
for (int i=0; i < 12; i++)
{
if (array[i] <= minimum)
minimum = array[i];
value = i;
}
return value;
}
}

You don't need to put that much work into the least and most methods. Instead, sort the arrays and pull from the first and last:
To get the month index for the most and least would be similar to what you have, but you don't take the values of.
Conflicting months where two match cannot be reported this way.

The hang is an infinite loop here: for (int i=0; i < 12; i = i++). Remove the assignment (or just use what I posted since I don't use a loop in that counter).

I'd give the averageRain an overload as well:

Also, in the future please choose a better topic title to describe the problem, and use [php][/php] or [code][/code] tags around code to preserve the formatting.
