Question

(Java)

Rewrite the following exercise to check the user inputs to be:

• Valid input

and

• positive

with using try-catch (and/or throw Exception )

**************************************************************************

Write a program to prompt the user for hours and rate per hour to compute gross pay. Calculate your pay computation to give the employee 1.5 times the hourly rate for hours worked above 40 hours.

Your code should have at least the following methods to calculate the pay. (VOID and NON-STATIC)

1. getInputs
2. calculatePay
3. printPay

Create an object of the class and declare the method as the instance methods.

Enter Hours: 45

Enter Rate: 10

Pay: 475.0

475 = 40 * 10 + 5 * 10*1.5

• Put at least two outputs (two different numbers and results)  (results after you run your code) at the end of your code as a multi-line comment.

/*

Your result

*/

Answer 1

SOURCE CODE IN JAVA:

import java.util.Scanner;

class Main

{

//variables to store user inputs and calculated values

int hours;

double rate, pay;

//function to get input from user and throw Exception for wrong input

void getInputs()throws Exception

{

    Scanner in=new Scanner(System.in);

    System.out.print("Enter hours: ");

    hours=in.nextInt();

    if(hours<0)

    throw new Exception("Hours cannot be negative!");

    System.out.print("Enter rate: $");

    rate=in.nextDouble();

    if(rate<=0)

    throw new Exception("Rate cannot be negative or zero!");

}

//function to calculate pay

void calculatePay()

{

    pay=hours*rate;

    if(hours>40)

    pay+=(hours-40)*rate*0.5;

}

//function to print pay

void printPay()

{

    System.out.println("Pay: $"+pay);

}

public static void main(String[] args)

{

    try

    {

      //calling the functions

      Main ob=new Main();

      ob.getInputs();

      ob.calculatePay();

      ob.printPay();

    }

    catch(Exception e) //catching any Exception thrown

    {

      System.out.println(e);

    }

}

}

OUTPUT:

Enter hours: 45 Enter rate: $10 Pay: $475.0
