Thread: Help splitting into two different classes.

Hello I am new here and to Java. I have a code I typed up and found out I need to use two originally written classes. I do not know where to split the code and how to call one class from the next. Can someone here help me?

package annualcompensation;

import java.util.Scanner; // import Scanner

public class AnnualCompensation { // initiate class AnnualCompensation


public static void main(String[] args) {//main method

Scanner input = new Scanner (System.in);// calls new scanner input

String FirstName;// holds first name
String LastName;// holds last name
Double BasePay = 50000.00;// holds base pay
Double CommPerc = .05;// holds commision percentage
Double CommAmou;// holds commision amount
Double AnnSales;//holds annual sales
Double TotalPay;// holds total pay
Double SalesTarget = 100000.00;// holds sales target

System.out.print("Enter First Name ");// calls for first name
FirstName = input.nextLine(); // accepts first name

System.out.print("Enter Last Name ");// calls for last name
LastName = input.nextLine();// accepts last name

System.out.print("Enter Annual Sales ");// calls for annual sales
AnnSales = input.nextDouble();// accepts annual sales amount

if (AnnSales >= 0.8 * SalesTarget && AnnSales <= SalesTarget)
{
CommAmou = AnnSales * CommPerc;
}
else if(AnnSales >= SalesTarget)
{
CommAmou = 1.25 * CommPerc * AnnSales;
}
else {
CommAmou = 0.00;
}// declares value for CommAmou

TotalPay = BasePay + CommAmou;// declares value for TotalPay

System.out.printf(FirstName + " " + LastName + " " +
"has earned a commision of $" + "%.2f\n", CommAmou);
// outputs name and commision amount

System.out.printf(FirstName + " " + LastName + " " +
"has earned an annual pay of $" + "%.2f\n\n", TotalPay);
// outputs name and total pay

System.out.println("Potential Salary Amounts\n");// outputs text
System.out.println("Total Sales \tTotal Compensation"); // outputs text

double Display = 5000 + AnnSales;// holds display value

while (Display <= 1.50 * AnnSales)// initiate loop to find display value
{
double Display2 = (Display * CommPerc)*1.25 + BasePay;
System.out.printf("%.2f\t%.2f\n", Display, Display2);
Display = Display + 5000;// diplay value increase by 5000

}// close while loop

}// close main method
}// close class AnnualCompensation

it's a good idea to seperate a model where you put the busisness logic (in your example : how you count the annualcompensation),
the I/O of your program (where you ask the data) and a place where you startup the program (in a console app where you
can find the main). Then you have also some of domain classes. In your example e.g the class Person.

When you want to use your program later in a other architecture (e.g Swing) you can still use your model and when
you want to make changes in your code it's easier to locate where you had to make the changes.
Maybe you think all these classes for a simple program. But in the view of maintaince the program it's the best way to do.
