Thread: Simple Salary Calculator Program

Hello, this is my first post on here, and I am new to java. I am trying to make a simple salary calculator that takes user input using the Scanner for the fields of entering an employee ID number, hourly pay, number of regular, and number of overtime hours worked. From there, it calculates the weekly pay with the employee ID number in the system.out somewhere. Here is what I have so far:

import java.util.Scanner;
 
public class PaymentCalculator {
	int employeeId;
	int regHours;
	int overHours;
	double wage;
	double totalPay;
 
	public static void main(String[] args) {
		System.out.println("Enter Employee ID: ");
		Scanner scan = new Scanner(System.in);
		int employeeId = scan.nextint();
		System.out.println("Enter the Number of Regular Hours: ");
		Scanner scan1 = new Scanner(System.in);
		int regHours = scan.nextint();
		System.out.println("Enter the Number of Over Time Hours: ");
		Scanner scan2 = new Scanner(System.in);
		int overHours = scan.nextint();
		System.out.println("Enter the Hourly Wage: ");
		Scanner scan3 = new Scanner(System.in);
		double wage = scan.nextdouble();
		double totalPay = (regHours * wage) + (overHours * (wage * 1.5));
		System.out.println("The total pay this week is: " + totalPay);
	}
}

I am using JCreator and am getting the errors:

--------------------Configuration: PaymentCalculator - JDK version 1.7.0_03 <Default> - <Default>--------------------
C:\Users\Bert\Documents\JCreator Pro\MyProjects\PaymentCalculator\PaymentCalculator .java:13: error: cannot find symbol

4 errors

Process completed.


Under the general output I am receiving:

--------------------Configuration: PaymentCalculator - JDK version 1.7.0_03 <Default> - <Default>--------------------
Error: Could not find or load main class PaymentCalculator

Process completed.


Any help with this would be much appreciated!

Okay, I am trying to make the program run from a few methods and I'm running into errors left and right:

}

I'm getting the error messages:

I've tried to fix the errors and I'm only getting more, any help would be much appreciated! Also, how can I do the loops mentioned in the post above?
