Lab Time: ArrayLists

• Make a Java class with arrays and loops.
• Declare and initialize an ArrayList object.
  
• Use JOptionPane.showInputDialog("prompt text"); to ask the user how many pets he or she has.
• Then, loop through the ArrayList, using JOptionPane.showInputDialog to ask the user for his or her pets' names.
• Add each name to the ArrayList with the add() method.
• Finally, print them out, using a for loop.
• Notes:
• You can do this all in one method if that makes it easier.
• Don't forget to have a public static void main(String args[]) method that will be called from the command line and will instantiate an object of your class.
• import javax.swing.*; at the very top of the program.  This will allow you to use the JOptionPane class in your program.
• import java.util.*; at the top of your program.  This will allow you to use the ArrayList class.
  
• The prompt to ask the number of pets should be outside and before your first loop.  This will tell you how many times to loop, so you should know this ahead of time!
• Assuming your ArrayList is named pets, the prompt and assignment should look something like this:

String petName = JOptionPane.showInputDialog("Enter the name for pet " + (i + 1) + ":");
pets.add(petName);
• This should be in the body of a for loop, and i should be the counter variable.
• Use another for loop to print out the names.  Thus, you should have two for loops total.
• Look at previous examples, or ask me for help!
