Question

(Intro to Java)

  • Open up Eclipse and create a new Java class called Salary.java.
  • Copy and paste the starter code below into the file.
  • NOTE: Do not change the starter code! All you need to do is add to it.
import java.util.Scanner;
public class Salary {
 
//Write your methods here
 
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int hours;
double hourly_wage;
double weekly_salary = 0;
double monthly_salary = 0;
double yearly_salary = 0;
System.out.println("This program will calculate your weekly, monthly "
+ "and yearly salary!");
System.out.print("Please enter your hourly wage: ");
hourly_wage = input.nextDouble();
System.out.print("Please enter the number of hours you work each week: ");
hours = input.nextInt();

//call methods below
weekly_salary = //method call goes here
monthly_salary = //method call goes here
yearly_salary = //method call goes here

System.out.printf("You make $%.2f per week\n", weekly_salary);
System.out.printf("You make $%.2f per month\n", monthly_salary);
System.out.printf("You make $%.2f per year\n", yearly_salary);
input.close();
}

}
  • Now write three methods as follows and place them above main:
weeklySalary():
  • Takes an integer argument for the number of hours worked each week
  • Takes a double argument for the hourly wage
  • Returns a double for the weekly salary

monthlySalary():
  • Takes an integer argument for the number of hours worked each week
  • Takes a double argument for the hourly wage
  • Calls the weeklySalary() method and multiplies the value it returns by 4 to calculate the monthly salary
  • Returns a double for the monthly salary
yearlySalary():
  • Takes in an integer argument for the number of hours worked each week
  • Takes in a double argument for the hourly wage
  • Calls the monthlySalary() method and multiplies the value it returns by 12 to calculate the yearly salary
  • Returns a double for the yearly salary
  • Assume that you work 12 months a year, without vacations
  • After you write each method, add a method call and store the result as the appropriate variable.

weekly_salary = //method call goes here
monthly_salary = //method call goes here
yearly_salary = //method call goes here

  • Now, run your code and verify that it prints the correct values for each salary type.
  • When you are finished, upload your file 
Your output should look identical to the following (except user input will vary):
This program will calculate your weekly, monthly, and yearly salary!
Please enter your hourly wage: 15
Please enter the number of hours you work each week: 40
You make $600.00 per week.
You make $2400.00 per month.
You make $28800.00 per year.
