Question

I need help with this problem please, This code needs to be in Ruby, Java, or Python. See problem below.

-5 - Functional Programming (due Mon] Assignment Content Your software company was invited to provide a proposal for a company in Australia. You currently have the cost in US dollars and need to convert the prices to the Australian dollar. Write a 2-part program using Ruby, Java, or Python. Part 1: Write a function to gather the following costs from the user: · Travel Cost: $9,800 • Hotel Cost: $3,500 • Rental Car Cost: $1,600 • Labor Cost: $15,500 Part 2: Write a function to convert the costs from United States dollar (USD) to Australian dollar (AUD). Note: Look up the current USD to AUD exchange rate to use in your function. I Test the program 3 times by providing different costs in USD. Provide the code and take a screenshot of the output, then paste the screenshot(s) into a Microsoft Word document. Write a half-page response in the same Microsoft Word document to address the following: • Provide a manual for the user explaining how to use the program. • Explain what type of user input validations you should have. What happens if the user enters a negative number? What happens if the user puts a $ in the input? Review the readings for this week from Ruby on Rails Tutorial or the Pluralsight videos if you have additional questions on deploying Ruby applications. Submit your document.

CODE :

import java.util.Scanner; //to get input from keyboard
class Main
{
/*************** DECLARE THE VARIABLES ***************/
   public static float travel,hotel,rental,labor;
/*************** GET COSTS (USD) PART 1 ***************/
   public void get_amount()
   {
       //the program will keep on asking for the input unless a non-negative value is inserted
      
       Scanner sc = new Scanner(System.in);
       while(1)
       {
           System.out.print("Enter the Travel Cost (USD) : ");
           travel = sc.nextFloat();
           if(travel>=0)
               break;
       }
       while(1)
       {
           System.out.print("Enter the Hotel Cost (USD) : ");
           hotel = sc.nextFloat();
           if(hotel>=0)
               break;
       }
       while(1)
       {
           System.out.print("Enter the Rental Car Cost (USD) : ");
           rental = sc.nextFloat();
           if(rental>=0)
               break;
       }
       while (1)
       {
           System.out.print("Enter the Labor Cost (USD) : ");
           labor = sc.nextFloat();
           if(labor>=0)
               break;
       }
      
   }
/*************** CALCULATE COSTS (AUD) PART 2 ***************/
   public void get_aud()
   {
       //the conversion rate of USD to AUD as of 18th Feb 2020 is 1.49 AUD per USD
       float conversion = (float)1.49;
       travel = travel*conversion;
       hotel = hotel*conversion;
       rental = rental*conversion;
       labor = labor*conversion;
   }
   public static void main(String args[])//DRIVER CODE
   {
       Main m = new Main();
       m.get_amount();
       m.get_aud();
       System.out.println("Travel Cost (AUD) = " + travel);
       System.out.println("Hotel Cost (AUD) = " + hotel);
       System.out.println("Rental Car Cost (AUD) = " + rental);
       System.out.println("Labor Cost (AUD) = " + labor);
   }
}
