Hello,
I've just started studying and I need help on one of my exercises.
I need the end user to input a rain fall number for each month. I then need to out put the average rainfall, highest month and lowest month and the months which rainfall was above average.
I keep getting the same number in the highest and lowest and I have no idea why. I am seriously pulling my hair out. Any help would be greatly appreciated.
This is what I have so far:
public class rainfall {
/**
* @param args
*/
public static void main(String[] args)
{
int[] numgroup;
numgroup = new int [13];
ConsoleReader console = new ConsoleReader();
int highest;
int lowest;
int index;
int tempVal;
int minMonth;
int minIndex;
int maxMonth;
int maxIndex;
System.out.println("Welcome to Rainfall");
for(index = 1; index < 13; index = index + 1)
{
System.out.println("Please enter the rainfall for month " + index);
tempVal = console.readInt();
while (tempVal>100 || tempVal<0)
{
System.out.println("The rating must be within 0...100. Try again");
tempVal = console.readInt();
}
numgroup[index] = tempVal;
}
lowest = numgroup[0];
for(minIndex = 0; minIndex < numgroup.length; minIndex = minIndex + 1);
{
if (numgroup[0] < lowest)
{
lowest = numgroup[0];
minMonth = minIndex;
}
}
highest = numgroup[1];
for(maxIndex = 0; maxIndex < numgroup.length; maxIndex = maxIndex + 1);
{
if (numgroup[1] > highest)
{
highest = numgroup[1];
maxMonth = maxIndex;
}
}
System.out.println("The average monthly rainfall was ");
System.out.println("The lowest monthly rainfall was month " + minIndex);
System.out.println("The highest monthly rainfall was month " + maxIndex);
System.out.println("Thank you for using Rainfall");
}
private static ConsoleReader ConsoleReader() {
return null;
}
}
Thanks,
Emily
