JAVA using assigned values from an array in a calculation

This is a very basic question but I have just started out with JAVA and have hit a bit of a bump with regards to arrays.

What I am trying to do is populate an array with 6 pieces of information from the user:

So far I have gotten these inputs into an array in JAVA however what I wanted to do was use corresponding number input to select a constant within the Pay Scale array and then use that constant to calculate the wages of each employee.

for instance employee 1 worked 10 hours at scale 0 so that would be 10*4.50 and employee worked 10 hours at scale 1 which would be 10*4.62

import java.util.Arrays; //imports Array utility
import java.util.Scanner; //imports Scanner utility

public class test1 {

    static Scanner keyb = new Scanner(System.in);   //Adds a keyboard input 

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter the number of Employees: ");
        int employees = scanner.nextInt();
        String[] Employee = new String[employees];
        String[] FirstName = new String[employees];
        String[] LastName = new String[employees];
        double[] HoursWorked = new double[employees];
        double[] PayScale = {4.50,4.62,4.90,5.45,6.20};


        for (int i = 0; i < Employee.length; i++) {
            System.out.print("Enter Employee Number: ");
            Employee[i] = scanner.next();
            System.out.print("Enter Employee's First name: ");
            FirstName[i] = scanner.next();
            System.out.print("Enter Employee's Last name: ");
            LastName[i] = scanner.next();
            System.out.print("Enter Employee's Hours worked: ");
            HoursWorked[i] = scanner.nextDouble();
            System.out.print("Enter Employee's Payscale (Number 0 to 4): ");
            PayScale[i] = scanner.nextDouble();
        }


        for (int i = 0; i < HoursWorked.length; i++) {
                System.out.println("Employee " + Employee[i] + " " + FirstName[i] + " " + LastName[i] + " has "
                        + HoursWorked[i] * PayScale[0]);

            }
        }
    }
}

Am I even close to a solution on this?

Is what I'm asking possible in JAVA?

Maybe I'm just looking at this the wrong way, but any help regarding this would be greatly appreciated.

edit

OK I added the extras array into the code Scanner scanner = new Scanner(System.in); System.out.println("Enter the number of Employees: "); int employees = scanner.nextInt(); String[] Employee = new String[employees]; String[] FirstName = new String[employees]; String[] LastName = new String[employees]; double[] HoursWorked = new double[employees]; int[]PayScale2 = {0,1,2,3,4}; double[] PayScale = {4.50,4.62,4.90,5.45,6.20};

I'm just unsure as to where I'd index the original PayScale array with the

PayScale[PayScale2[i]]

would it go into the for statement codeblock? (I have tried putting it in there however I get an error that it's not a statement :/

change 

+ HoursWorked[i] * PayScale[0]);

to 

+ HoursWorked[i] * PayScale[i]);

apart from that seems to me like you're doing what you're saying you should be doing..

you already have the payscales from here: double[] PayScale = {4.50,4.62,4.90,5.45,6.20}; so the following doesn't make a lot of sense: 

System.out.print("Enter Employee's Payscale (Number 0 to 4): ");
            PayScale[i] = scanner.nextDouble();

First of all, if you want to keep this number (Number 0 to 4) separately, you should use another Array, not the one where you keep the Payscales, then you could index to the first array which keeps the different rates.. or else you could directly use the first array if you know the pay scale for every employee.. in the end it has to do with what you want to do and how you want to do it, but the logic and the tools are there. If you call the 2nd array PayScale2 for example:

 System.out.print("Enter Employee's Payscale (Number 0 to 4): ");
            PayScale2[i] = scanner.nextDouble();

then you can index to the first array for example:

PayScale[PayScale2[i]]

in which case if the user inputs 0 then PayScale2[i] would be 0 then PayScale[PayScale2[i]] would be PayScale[0] or 4.5 or whatever you set the value equal to at the first array
