Thread: I have a problem with this Joption programme.

I'm trying to create program that allows you to enter a 12 digit number, e.g. xxxxxxxxxxxy... then it asks you to verify the number (but this time you only enter the first 11 digits of the same number) e.g. xxxxxxxxxxx. Then it will take the last digit of the first entry and put it together with at the end of the second entry so it can give you the full 12 digit number.
If the numbers match it will tell you the ticket is valid.. if not it will tell you the ticket is invalid.

Alright this is the code... When i compile it i get 14 errors:

import javax.swing.JOptionPane;
import javax.swing.JFrame;
 
public Validation
{
public static void main(String[] args) throws Exception
{
//Declaration of strings
String inputOne;
String inputTwo;
 
//Declaration of long numbers
long ticket;
long confirm;
 
//Declaration of integers
int remainder = ticket%10;
 
inputOne=JOptionPane.showInputDialog("Please enter the 
 
ticket number: ");
inputTwo=JOptionPane.showInputDialog("Please confirm the 
 
ticket number: ");
 
ticket=long.parseLong(inputOne);
confirm=long.parseLong(inputTwo);
 
if ((confirm+remainder)==ticket)
{
JOptionPane.showMessageDialog(null, "The ticket number you 
 
just entered is valid", JOptionPane.INFORMATION_MESSAGE);
}
else
{
JOptionPane.showMessageDialog(null, "The ticket number you 
 
just entered is invalid", JOptionPane.INFORMATION_MESSAGE);
}
{
System.exit(0);
}
}
}

And what errors might these be? On what lines?

I've edited your post to include highlight tags. Please be more mindful in the future.

Did you google these Exceptions?

Hint: What does a class declaration look like?

You are missing a keyword. Recommended reading: Classes (The Java™ Tutorials > Learning the Java Language > Classes and Objects) and Declaring Classes (The Java™ Tutorials > Learning the Java Language > Classes and Objects)
