can someone look at this script? JAVA

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

//make the string input
public static void main(String[] args){

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[4]; // Space for 100 ints.
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(numbers);
}

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);

}

public static void aveArray(double rad[]){
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
avg = sum/rad.length;
}
JOptionPane.showMessageDialog(null,"The average of the prices is " + avg);

}

public static void highPrices(double rad[]){

// double avg; // 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
// avg = sum/rad.length;
// }
JOptionPane.showMessageDialog(null,"ddd" + avg);





System.exit(0);


}

}


The high price array doesnt work --- i need it to recieve and average from the aveArray() and the Array numbers[] and retuen the numbers whose value is greater then the average to the main method.

Can anyone point me in the right direction?

Did you received any error message talking about variable "sum"?

I said so because you didn't declared "sum" in "public static void highPrices" function.

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

//make the string input
public static void main(String[] args){

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[4]; // 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();
}

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);

}

public static void aveArray(double rad[]){
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
avg = sum/rad.length;
}
JOptionPane.showMessageDialog(null,"The average of the prices is " + avg);

}

public static double highPrices(double arr[]){

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
avg = sum/rad.length;
}
int len;
int a, b;
numbers temp;
double high = len - 1;
for(a = 0;a <high; ++a)
for(b = 0; b < high; ++b)
if(numbers[b] >[b + 1])
{
temp = numbers[b];
numbers[a] = numbers[b + 1];
numbers[b+1] = temp;
}

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





System.exit(0);

}

}


im having trouble with the highprices () it is supposed to take the ave and the array and display the numbers higher then the average.
If anyone can show me how to do this it would be great.

Thanx
