Question

Lab Directions:

Complete each of the programs here. Create a separate Netbeansproject for each program using the name I specified. Create a single java main class for each of the programs using the filename I specified.

Task 1: (5 points)

Project name: CtoFConverter
Main file name: TempConverter.java

A program that converts an inputted temperature in C and provides the equivalent temperature in F. Hint: Google is your friend! Given C, solve for F. Again, check for a valid input value and only respond with the F value if you got it, otherwise output an appropriate error msg to the user. Testing: 3 conditions: Bad Input, then test for the known freezing and boiling points.

EMBED SCREEN SHOT(S) OR COPY THE OUTPUT WINDOW OF NETBEANS HERE SHOWING YOUR PROGRAM TEST RUN(S):

Task 2: (5 points)
Project name: FuelCosts
Main file name: FuelCost.java

Write a program that asks the user to input

• The number of gallons of gas currently in the tank

• The fuel efficiency in miles per gallon

Then print how far the car can go with the gas in the tank. Again, check for valid input and exit with an error msg if you do not have it. Testing: here just use some reasonable values that you can inspect the calculations and determine they are correct.

Submitting your work:

Create a new compressed .zip archive folder. (Don’t give me any other type of archive, it will be returned to you ungraded!) called Lastname_Firstname_Lab_06.zip using your name.  

Place both of your Netbeans project folders in this archive. (Do not individually zip the projects!) Place this word doc file with your screen shots in the archive as well. (Don’t put this in the individual project folders, put it in the top level in the archive so I can access it easily.)

(When I open you archive I should see each of your project folders in it and this file.)

Submit the one Zip file (with both NetBeans projects and the Word document) for your grade.

Answer 1

1. CODE IN JAVA:

TempConverter.java file:

import java.util.Scanner;

public class TempConverter {

   public static void main(String[] args) {
       // creating object to the Scanner class to take input from the user
       Scanner sc = new Scanner(System.in);
       // taking temperature in celcius as input from the user
       System.out.print("Enter temperature in celcius:");
       double celcius = sc.nextDouble();
       // converting celcius to fahrenheit
       double fahrenheit = ((celcius * 9) / 5) + 32;
       // displaying the temperature in Fahrenheit
       System.out.printf("Corresponding temperature in fahrenheit:%.2f\n", fahrenheit);

   }

}

OUTPUT:

2. CODE IN JAVA:

FuelCost.java file:

import java.util.Scanner;

public class FuelCost {

   public static void main(String[] args) {
       // creating object to the Scanner class to take input from the user
       Scanner sc = new Scanner(System.in);
       // taking input from the user
       System.out.print("Enter the number of gallons of gas currently in the tank:");
       double num = sc.nextDouble();
       System.out.print("Enter the fuel efficiency in miles per gallon:");
       double efficiency = sc.nextDouble();
       // calculating travel distance of the car
       double distance = num * efficiency;
       // displaying the travel distance
       System.out.println("The car can travel maximum " + distance + " miles");

   }

}

OUTPUT:
