Calling methods from another class

Greetings List,

Just joined this forum. Just using Java as a student. Having problems with =
some code I wrote. Here is the code. Not sure if this is the way to post to=
 this forum. Correct me if I'm wrong, and I'll edit my post appropriately.=
 

<---------------------------Code is Below----------------------------------=

I have a very standard Lab assignment. It's probably been seen a lot. I wro=
te the first part not realizing I had to write a second class to do use the=
 methods. I'm not sure how to change my program to call methods from my sec=
ond class instead of doing all my calculations with user input in my first =
class.

Here's the first class' code:
[highlight=Java]
package tickets;

/**
 *
 * @author steven.
 */

//Imports classes used for "Ticket" application.

import java.util.*;
import java.text.DecimalFormat;

public class Tickets {

    /**
     * This is the base of my application.
     */
    public static void main(String[] args) {
        // Create a scanner object to get input from user.
        
        Scanner input = new Scanner(System.in);
        
        //Declares variables for seating.
        
        int a, b, c;
        
        //Declares doubles to store user input and store sales total in.
        
        double A, B, C, salesTotal;
        
        //User input for amount sold and price of "A" tickets.
        
        System.out.print("Enter number of A tickets sold, please.");
        a = input.nextInt();
        System.out.print("Enter price of A tickets, please.");
        A = input.nextDouble();
        
        //User input for amount sold and price of "B" tickets.
        
        System.out.print("Enter number of B tickets sold, please.");
        b = input.nextInt();
        System.out.print("Enter price of B tickets sold, please");
        B = input.nextDouble();
        
        //User input for amount sold and price of "C" tickets.
        
        System.out.print("Enter number of C tickets sold, please.");
        c = input.nextInt();
        System.out.print("Enter price of C tickets, please");
        C = input.nextDouble();
        
        //This calculates the total sales for all tickets sold.
        
        salesTotal = ((a*A)+(b*B)+(c*C));
        
        //Displays Total Sales and seats.
        
        System.out.println("Number of A tickets sold: "+ a);
        System.out.println("Number of B tickets sold: "+ b);
        System.out.println("Number of C tickets sold: "+ c);
        System.out.println("Total ticket sales: " + salesTotal);
        
        //
    }
    
}

That code works fine, compiles without errors and correctly calculates and =
displays everything correctly. I didn't realize I needed to implement a sec=
ond class in this program. Here is my attempt:

[highlight=Java]
package tickets;

/**
 *
 * @author Steven
 */
public class Seats {
    //Declare data members.
    
    private int seats;
    
    //Constructors.
    
    public Seats()// My default constructor.
    {
            seats = 0;
    }
    public Seats(int numSeats)
    {
       setSeats(numSeats);
    }
    
     //instance methods
    public void setSeats(int numSeats)
    {
     //validate parameter
        seats = numSeats;
    }
    public int getSeats()
    {
        return seats;
    }
    
    public int computeSeats()
    {
        return seats + seats + seats;
    }
    
    public void setPrice(double priceSeats)
    {
        private double price;
        
    }
    
}
[/highlight]

The code is obviously incomplete. I have not tried to compile, nor would I =
expect it to compile right. I'm not sure how to move my calculations from t=
he first class shown above into my second class and use them as methods. Ca=
n someone please help? Am I moving in the right direction?

Thanks a lot. I appreciate someone that knows what they're doing to tell me=
 what I need to do.
