Question

Complete each of the programs here. Create a separate Netbeans project 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.

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.

Answer 1

Here is your required code in JAVA:

A)

import java.util.Scanner;

public class TempConvertor
{
// converts Celsius to Fahrenheit scale
static float convert(float n)
{
return ((n * 9.0f / 5.0f) + 32.0f);
}
  
// Driver code
public static void main(String[] args) {
  
Scanner sc = new Scanner(System.in);
  
//number of test cases
//chnage accordingly
int t=4;
for(int i=0;i<t;i++)
{
try
{
float c;
System.out.println("\nTest Case "+i+": ");
System.out.print("Enter temperature in Celsius: ");
  
//taking input
c = sc.nextFloat();
  
//displaying output
System.out.println("Temperature in Fahrenheit: " + convert(c));
}
catch(Exception e)
{
//displaying error
System.out.println("Error: Bad Input!");
}
}
}
}

B)

import java.util.Scanner;

public class FuelCosts
{
// calculate maximum distance that can betraveled
static double max_dis(double fuel, double efficiency)
{
return efficiency * fuel;
}
  
// Driver code
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
  
//number of test cases
//chnage accordingly
int t=4;
for(int i=0;i<t;i++)
{
try
{
float f, e;
Exception ex = new Exception();
  
System.out.println("\nTest Case "+i+": ");
System.out.print("Enter gallons of Fuel in tank: ");
//taking input
f = sc.nextFloat();
if(f<0)
throw ex;
  
System.out.print("Enter efficiency in miles per gallon: ");
//taking input
e = sc.nextFloat();
if(e<0)
throw ex;
  
//displaying output
System.out.println("Maximum Distance that can be covered: " + max_dis(f, e));
}
catch(Exception e)
{
//displaying error
System.out.println("Error: Bad Input!");
}
}
}
}
