Using arrays to declare name and address

[Joshua Perrine]

Trying to use arrays to declare name/address and to populate it

import javax.swing.JOptionPane;
public class P3MailOrderSOLN
{
    public static void main(String[] args)
    {
        // Declare variables
        String title, firstName, lastName, streetAddress, city, state, zip;
        int numBoxes;
        String numBoxesInput;
        int count;
        String enterAnother;
        //  Loop to gather label input
        enterAnother = "Y";
        while (enterAnother.equalsIgnoreCase("Y"))
        {
            title = JOptionPane.showInputDialog(
                "Enter title (Mr., Ms., Dr., etc.):");
            firstName = JOptionPane.showInputDialog("Enter first name:");
            lastName = JOptionPane.showInputDialog("Enter last name:");
            streetAddress = JOptionPane.showInputDialog(
                "Enter the street address:");
            city = JOptionPane.showInputDialog("Enter the city:");
            state = JOptionPane.showInputDialog("Enter the state:");
            zip = JOptionPane.showInputDialog("Enter the zipcode:");
            numBoxesInput = JOptionPane.showInputDialog(
                "Enter the number of boxes to be mailed:");
            numBoxes = Integer.parseInt(numBoxesInput);
            //  Loop to produce the set of labels
            count = 1;
            while (count <= numBoxes)
            {
                System.out.println(title + " " + firstName + " " + lastName);
                System.out.println(streetAddress);
                System.out.println(city + ", " + state + " " + zip);
                System.out.println("Box " + count + " of " + numBoxes);
                count = count +1;
            }
            //  Ask if want to produce more labels
            enterAnother = JOptionPane.showInputDialog(
                "Do you want to produce another set of labels? Y or N");
        }  //  User said no mas (no more labels to produce :o)
        System.exit(0);
    }  // end of main() method
}  //  end of public class

I don't see an array declared anywhere (?). Do you know how to declare an array?

Also, when you post code you need to enclose it in "Code" tags. Above the edit window are some buttons, one of which is Code. First highlight your code, then click that button.

I don't know how to declare an array confused on how to here

[Carey Brown]

To declare an array of int's

int[] myArray = new int[ 10 ];

The first "[]" says we are declaring an array, and the "[ 10 ]" allocates room for 10 int's'.

You have

String title, firstName, lastName, streetAddress, city, state, zip; 

You could make each one an array but you'd be asking for trouble trying to keep them in sync.
The best approach is to define a class (e.g.) Person with those fields. and then allocate one array of Person objects.

Person[] people = new Person[ 10 ]; // or whatever size you need

[Joshua Perrine]

still confused on how to implement this into my code.

I suggest you Google "java array tutorial" and study some of those. This TUTORIAL looked good. I also suggest writing some very small programs to practice, put your current project aside for now.

import java.util.Scanner;

public class ArrayBeginner
{
	public static void main( String[] args )
	{
		Scanner			keyboard = new Scanner( System.in );
		
		System.out.print( "How many names do you want ? " );
		int				qty = keyboard.nextInt();
		keyboard.nextLine(); // flush pending new-line
		
		String[]		names = new String[ qty ];
		
		for( int i=0 ; i < names.length ; i++ )
		{
			System.out.print( "Enter a name: " );
			names[ i ] = keyboard.nextLine();
		}
		
		for( int i=0 ; i < names.length ; i++ )
		{
			System.out.println( i + " = " + names[i] );
		}
	}
}

You need to declare the array, that's why you're getting errors. Hope this helped!

When you post, be sure it adds something to the thread.  This advice was already given.
