Question

Basically I am trying to create a new class as long as the continue variable equals “Y”. The problem I am having is

DigitalMain.java:18: not a statement
    DigitalPhoto[] class = new DigitalPhoto[9];

upon compile. I have looked at ArrayLists but I am not quite sure if they would instantiate classes the same way as what I am trying to achieve. In an ideal situation I would have objects with the name “class”+i, and different values for every object via their built in set methods.

// Import classes for class
import java.util.Arrays;
import java.util.List;
import javax.swing.*;
import java.awt.event.*;
import java.text.DecimalFormat;

public class DigitalMain
{
  public static void main(String args[])
  {
    String cont = "Y";
    String heightString,widthString,width,bitpsString;
    double bitps,x,y,totesPrice,totesSize,totesSpeed;
    DecimalFormat wholeDigits = new DecimalFormat("0");
    DecimalFormat dec = new DecimalFormat("0.00");

    DigitalPhoto[] picc = new DigitalPhoto[20];
    for(int i=0; cont.equals("Y") ; i++)
    {
    picc[i] = new DigitalPhoto();
    heightString = JOptionPane.showInputDialog("Please enter height");
    picc[i].setHeight = Double.parseDouble(heightString);
    heightString = JOptionPane.showInputDialog("Please enter width");
    picc[i].setWidth = Double.parseDouble(widthString);
    continueQuestion = JOptionPane.showInputDialog("Height: " + picc[i].getHeight + "\n Width: " + picc[i].getWidth + "\n Resolution: " + picc[i].getResolution + "\n Compression Ratio: " + picc[i].getCompression + "\n Required Storage: " + picc[i].calcStorage() + "\n Price of Scanned Photo: " + picc[i].getCost() + "Please enter 'Y' to try again or anything but 'Y' to accept values.");
    };


    do
    {
    bitpsString = JOptionPane.showInputDialog("Please enter your internet connection speed. Must be an integer between 1 and 99999999");
    bitps = Double.parseDouble(bitpsString);
    } while (bitps > 0 && bitps < 99999999);
    picc0.setSpeed(bitps);

    for(y = 0; y<picc.length; y++) {
      totesPrice += picc+y.getCost();
      totesSize += picc+y.calcStorage();
      totesSpeed = picc0.getSpeed();
    }

    double seconds = transferTime(totesSize, totesSpeed);
    double minutes = seconds / 60;
    double realsec = seconds % 60;

    JOptionPane.showMessageDialog(null, "You will be paying: " + totesPrice + "\nRequired Storage is: " + totesSize + "Required time for transfer is: " + wholeDigits.format(minutes) + " minutes, and " + wholeDigits.format(realsec) + " seconds.");

  }

  public static double transferTime(double totalStorage, double netSpeed) {
    double bits, seconds;
    bits = (totalStorage * 8);
    seconds = (bits / netSpeed);
    return seconds;
    };
}

The issue is most likely the name of your array. The word class is a keyword in the Java language and hence cannot be used to name variables. You can also use ArrayLists like so:

List<DigitalPhoto> photoes = new ArrayList<DigitalPhoto>(); 
do
    {
    DigitalPhoto photo = new DigitalPhoto();
    heightString = JOptionPane.showInputDialog('Please enter height');
    photo .setHeight = double.parseDouble(heightString);
    heightString = JOptionPane.showInputDialog('Please enter width');
    photo .setWidth = double.parseDouble(widthtString);
    photos.add(photo)
    continueQuestion = JOptionPane.showInputDialog('Height: ' + class[i].getHeight + '\n\lWidth: ' + class[i].getWidth + '\n\l Resolution: ' + class[i].getResolution + '\n\lCompression Ratio: ' + class[i].getCompression + '\n\lRequired Storage: ' + class[i].calcStorage() + '\n\lPrice of Scanned Photo: ' + class[i].getCost() + 'Please enter "Y" to try again or anything but "Y" to accept values.')
    } while {cont.equals("Y")};
