    Default Please help... Can somebody fix this for me?

    Can somebody show me how this one is done. I don not know how to do the rest. I have attached what I have so far. Would highly appreciate it. I would like it to print out an amount.

    Write a rainfall class that stores the total rainfall for each of 12 months into an array of doubles. The program should should have methods that return the following:
    1. the total rainfall for the year
    2. the average monthly rainfall
    3. the month with the most rain
    4. the month with the least rain

    Demonstrate the class in a complete program

    Input Validation: Do not accept negative numbers for monthly rainfall figures.


    public class Rainfall {

    double monthlyAmount[] = new double[12];

    public Rainfall() { }

    public void setMonthlyAmount(int monthNo, double amt) {
    monthlyAmount[monthNo] = amt;
    }

    public double getTotalRainfall() {
    double total = 0.0;
    for (int i = 0; i < monthlyAmount.length; ++i)
    total += monthlyAmount[i];
    return total;
    }

    public double getAverageRainfall() {
    return getTotalRainfall() / (double) monthlyAmount.length;
    }

    public double getLeastRainMonth() {
    int minIdx = 0;
    double minAmt = monthlyAmount[0];
    for (int i = 1; i < monthlyAmount.length; ++i) {
    if (monthlyAmount[i] < minAmt) {
    minAmt = monthlyAmount[i];
    minIdx = i;
    }
    int most_rain_month = 11;
    for(int i = 0; i < 11; i++) {
    if ( monthlyAmount[i] > monthlyAmount[most_rain_month] )
    most_rain_month = i;

    }

    return minAmt;
    }

    public double getMostRainMonth() {
    int maxIdx = 0;
    double maxAmt = monthlyAmount[0];
    for (int i = 1; i < monthlyAmount.length; ++i) {
    if (monthlyAmount[i] > maxAmt) {
    maxAmt = monthlyAmount[i];
    maxIdx = i;
    }
    }
    return maxAmt;
    }
    }

    Please edit your code and wrap it in code tags. See: BB Code List - Java Programming Forums

    Does the program compile without errors? If not, copy and paste them here.
    What does the program currently output? Please copy and paste its output here.

    I don not know how to do the rest.
    Please explain what parts are missing and why you are having problems with them.
