    Default JOption help

    Please don't bash me for I am new to Java. I am learning but am lost on a simple problem I'm sure. We have been working with a basic text editor and getting our results to show up on the consel. No problem. Now with little knowledge we are supposed to get our code to show up in dialog boxes using import javax.swing.JOptionPane; I have tried many time and been reading online on how to do it but I keep getting all sorts of errors. The book i have does not talk much about JOption. So I went back and put my code back to what I had originally. My code is posted below and any help would be much appreciated. Like I said, I am new and still learning but have been stuck here for a few days getting confused after reading all sorts of stuff online. Thanks in advance! I also want to try and be able to enter a interest rate and have it display in the last message but that is giving me trouble too.

    import javax.swing.JOptionPane;
    import java.util.Scanner;

    public class RetirementGoal2
    {

    public static void main(String[] args)
    {


    Scanner sc = new Scanner(System.in);

    int year;
    double money;

    do {
    System.out.print("Enter number of years before retirement: ");
    year = sc.nextInt();
    System.out.print("Enter annual amount of money: ");
    money = sc.nextDouble();
    if (year < 1 || money <= 0)
    {
    System.out.println();
    System.out.println("ERROR: Invalid input. Enter new values again.");
    System.out.println();
    }

    }
    while (year < 1 || money <= 0);

    for (int x = 1; x <= year; x++)
    {
    for (int y = 0; y < x; y++)
    money += money * 0.05;
    }
    System.out.println();
    System.out.println("You will have $" + money +
    " at retirement.");
    }
    }

    I keep getting all sorts of errors.
    Please copy the full text of the error message and paste it here. It has important info about the error.

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

    Please post your code correctly using code or highlight tags per the above link.

    No bashing here. We can't really help you with the code that works - there's nothing broken to help you fix. Post the code and the errors, as Norm said, so that we can help you fix code that's broken.
