import java.util.*;
import javax.swing.JOptionPane;
//create a class
public class prices {

//make the string input
public static void main(String[] args){
double nag= 0;
String Input;
double[] numbers; // An array for storing the input values.
int numCt; // The number of numbers saved in the array.
double num; // One of the numbers input by the user.

numbers = new double; // Space for 5 doubles.
numCt = 0; // No numbers have been saved yet.

Input = JOptionPane.showInputDialog(null, "Please enter a price.");

while (numCt < numbers.length) { // Get the numbers and put them in the array.
Input = JOptionPane.showInputDialog(null, "Please enter a price.");
num = Double.parseDouble(Input);
if (num <= 0)
break;
numbers[numCt] = num;
numCt++;
}
sumArray(numbers);
aveArray(numbers);
//highPrices();
JOptionPane.showMessageDialog(null,"ddd" + nag);
}

public static void sumArray(double arr[])
{

double sum = 0; // Start the total sum at 0.
for (int i=0; i<arr.length; i++) {
sum = sum + arr[i]; // Add the next element to the total
}
JOptionPane.showMessageDialog(null,"The sum of the prices is " + sum);

}

double avg = 0;

double sum = 0; // Start the total sum at 0.
for (int i=0; i<rad.length; i++) {
sum = sum + rad[i]; // Add the next element to the total
}
JOptionPane.showMessageDialog(null,"The average of the prices is " + avg);

}

public static double highPrices(){

double avg = 0;

double sum = 0; // Start the total sum at 0.
for (int i=0; i<arr.length; i++) {
sum = sum + arr[i]; // Add the next element to the total
avg = sum/arr.length;
if(avg < arr[i])
return nag;

//JOptionPane.showMessageDialog(null,"ddd" + ave);
