How do I go about defining the average and total variables in the following script? Assistance is appreciated... Ben

import javax.swing.JOptionPane;

class minmax {

/** Main Method */

public static void main(String[] args)

{

final double TOTAL_NUMBERS = 5;

//Convert string to double

double Average = Double.parseDouble(averageString);

//Convert string to double

double total = Double.parseDouble(totalString);

// Prompt the user to enter a double value

for (int i =0; i < numbers.length;i++) {

String doubleString = JOptionPane.showInputDialog(null,

"Enter a double value","Input (double)",

JOptionPane.QUESTION_MESSAGE);

}

// Find the largest

int doubles = numbers[0];

for (int i = 1; i < doublenumbers.length; i++) {

if (doubles < numbers*)
doubles = doublenumbers ;
}*

// Find the smallest

int doubles = numbers[0];

for (int i = 1; i < numbers.length; i++) {

if (doubles < numbers*)
doubles = numbers ;
}*

// Prepare the results

String output = "The values are ";

for (int i = 0; i < numbers. length; i++) {

output += numbers* + " ";
}*

output += "\nThe largest number is " + doubles;

output += "\nThe smallest number is " + doubles;

output += "\nThe average number is " + average;

output += "\nThe total number is " + total;

// Display results

JOptionPane.showMessageDialog(null,doublevalue +

"Output", JOptionPane.INFORMATION_MESSAGE);

}

}
