Question

(Salary Calculator) Develop a Java application that determines the gross pay for each of three employees. The company pays straight time for the first 40 hours worked by each employee and time and a half for all hours worked in excess of 40. You’re given a list of the employees, their number of hours worked last week and their hourly rates. Your program should input this information for each employee, then determine and display the employee’s gross pay. Use class Scanner to input the data.

Answer 1

Program

import java.util.ArrayList;
import java.util.Scanner;

/*for storing deatils about the employees*/
class EmployeeDetails{
   private String name;
   private double hoursWorked, payRate;
  
   public EmployeeDetails(String name, double hoursWorked, double payRate) {
       this.name = name;
       this.hoursWorked = hoursWorked;
       this.payRate = payRate;
   }
  
   public double calculateGrossPay() {
       double payment = 0;
       //calculating gross pay as per instruction
       if(hoursWorked > 40)
           payment = payment + (hoursWorked * (1.5 * payRate));
       else
           payment = payment + (hoursWorked * payRate);
      
       return payment;
   }

   @Override
   public String toString() {//for showing output
       return "Name=" + name + "\nHours Worked=" + hoursWorked + "\nPay Rate= $" + payRate
               + "\nGross pay= $" + calculateGrossPay();
   }
  
  
}

public class Test {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
      
       int size;
       String name;
       double payRate, hoursWorked;
      
       //for storing details in the arraylist
       ArrayList ar = new ArrayList<>();
      
       System.out.print("Enter the number of Employees: ");
       size = sc.nextInt();
       for(int i=0; i            sc.nextLine();
           System.out.print("Enter name: ");
           name = sc.nextLine();
           System.out.print("Enter hours worked: ");
           hoursWorked = sc.nextDouble();
           System.out.print("Enter pay rate: ");
           payRate = sc.nextDouble();
          
           ar.add(new EmployeeDetails(name, hoursWorked, payRate));
           System.out.println();
       }
      
       //output
       System.out.println("Employee Details and Gross pay");
       System.out.println("--------------------------------");
       for(EmployeeDetails i: ar) {
           System.out.println(i);
           System.out.println("--------------------------------");
       }
       sc.close();
   }
}

Output
