Question

I've seen this question answered for C but I don't know how to translate to Java.

Write a program that requests the hours worked in a week and the basic pay rate, and then prints the gross pay (before tax), the taxes, and the net pay (after tax).

Assume the following:

1. Basic pay rate: from user's choice
2. Overtime (in excess of 40 hours) = time and a half (i.e., if the hours worked is 45, the hours for pay will be 47.5, which is 40 + 5 * 1.5).
3. Tax rate:
   • 15% of the first $300;
   • 20% of the next $150;
   • 25% of the rest.

                final double TAX_RATE_2 = 0.20;
                final double TAX_RATE_3 = 0.25;         
                final double TAX_BREAK_1 =      300;
                final double TAX_BREAK_2 =      450;
                
                //Declare variables

                double hoursPay = 0; //The times for pay, i.e., one and a half for each hour overworked
                double grossPay = 0;
                double netPay = 0;
                double tax = 0;
                                
                //Display the choices of basic tax rate
                //Accept user's choice of pay rate and set up the basic pay rate
                //Ask user for the hours worked
                //Calculate the hours for pay: 
                //If the hours worked is less than or equals to 40, same as is
                //if it's greater than 40, hoursPay = 40 + (hoursWorked - 40) * 1.5
                //Calculate the gross pay
                //Calculate the tax
                //Calculate the net pay
                //Display the result

Code

import java.util.Scanner;

public class Pay {

public static void main(String[] args) {
//Constants
final int NORMAL_WORK_HOURS = 40;
final double OVERWORKED_TIMES = 1.5;
final double TAX_RATE_1 = 0.15;
final double TAX_RATE_2 = 0.20;
final double TAX_RATE_3 = 0.25;   
final double TAX_BREAK_1 = 300;
final double TAX_BREAK_2 = 450;
  
//Declare variables
Scanner sc = new Scanner(System.in);
int userChoice = 0;
double payRate = 0;
double hoursWorked = 0;//The actual hours worked
double hoursPay = 0; //The times for pay, i.e., one and a half for each hour overworked
double grossPay = 0;
double netPay = 0;
double tax = 0;
  
//Accept user's choice of pay rate and set up the basic pay rate
System.out.print("Enter your pay rate: ");
payRate=sc.nextDouble();
//Ask user for the hours worked
System.out.print("Enter weekly hours worked: ");
hoursWorked=sc.nextDouble();
//Calculate the hours for pay:
if(hoursWorked>40) //if it's greater than 40, hoursPay = 40 + (hoursWorked - 40) * 1.5
   hoursPay=NORMAL_WORK_HOURS+(hoursWorked-NORMAL_WORK_HOURS)*OVERWORKED_TIMES;
else //If the hours worked is less than or equals to 40, same as is
   hoursPay=hoursWorked;
  
grossPay=hoursPay*payRate;
  
//Calculate the tax
if(grossPay>TAX_BREAK_2)
{
   tax=75+(grossPay-TAX_BREAK_2)*TAX_RATE_3;
}
else if(grossPay>TAX_BREAK_1)
{
   tax=45+(grossPay-TAX_BREAK_1)*TAX_RATE_2;
}
else {
   tax=grossPay*TAX_RATE_1;
}
  
//Calculate the net pay
netPay=grossPay-tax;
//Display the result
System.out.printf("Gross pay :$%,.2f%n",grossPay);
System.out.printf("Tax :$%,.2f%n",tax);
System.out.printf("Net pay :$%,.2f%n",netPay);
}

}
