dialog boxes and two users

[Holly Leery]

Ok below is a code i have been trying to put together. I want there to be two seprate users that as dialog boxes pop up they enter their first name then last and then their age. Each user does that and then in the end i want to compare the ages and the last dialog box to say:

First Person: Smith, John (31)
Second Person: Doe, Mike (35)
Doe is older than Smith


So here is my code and i know i have serveral errors, can someone help me?

 
// This program prompts the user to enter their first and last name
// plus thier age and compare the two values
  
 import javax.swing.*;
 
 public class HW1 {
     
     // access modifier
     public static void main( String[] args ) {
         
         String firstName1;//first string entered by user1
 String lastName1;//second string entered by user1
 String age1;//thrid string entered by user1
 int age1;//first age entered by user1 
  
 String firstName2;//first string entered by user2
 String lastName2;//second string  entered by user2
 string age2;//third string entered by user2
 int age2;//first age entered by user2
         
 //read in first name by user1 as a String
 firstName1 =
JOption.showInputDialog("Please enter your first name");
 
 
 //read in last name by user1 as a String
 lastName1 =
JOption.showInputDialog("Please enter your last name");

 
 //read in age by user1 as a String
 age1 =
JOption.showInputDialog("Please enter your age");
 

 //read in first name by user2 as a String
 firstName2 =
JOption.showInputDialog("Please enter your first name");
 

 //read in last name by user2 as a String
 lastName2 =
JOption.showInputDialog("Please enter your last name");

 
 //read in age by user2 as a String
 age2 =
JOption.showInputDialog("Please enter your age");
  
 //convert ages from type String
age1 = Intger.parseInt( age1 );
age2 = Integer.parseInt(age2 );
  
//compare the two ages
         // boolean comparison statement
         if ( age1 > age2 )
            // give the statement that will be executed ONLY IF
            // age1 is greater than age2
            message = "First user is older than the second.";
         
         if ( age1 < age2 )
            message = "Second user is older than the first.";
         
         if ( age1 == age2 )
            message = "First user is the same age as the second.";

 
         // report the result back to the user
         JOptionPane.showMessageDialog( null, message );
         
         // quit the program
         System.exit( 0 );
     }
 }

That's really not too bad. The main problem is that you're assigning the value returned from showInputDialog() directly to age1 and age2, which are integers. You'll need separate String variables to hold the String values, and pass those values to parseInt() and assign the return values of parseInt() to the ageX variables.

Make sense?

sort of...im a little lost? so i put the dialog boxes in string variables and ages in a different variable? sorry im a little a slow at this. im new so i dont really know what everything means i have to go and look it up.
