Write a program to convert a fraction to a decimal. Have your program ask for the numerator first, then the denominator. Make su
Anton [14]
<h2>Answer:</h2>

import java.util.Scanner;

public class FractionToDecimal {

   public static void main(String[] args) {

       Scanner input = new Scanner(System.in);

       

       System.out.println("Please enter the numerator");

       double numerator = input.nextDouble();

       System.out.println("Please enter the denominator");

       double denominator = input.nextDouble();

       

       if(denominator == 0){

           System.err.println("ERROR - Cannot divide by zero.");

       }

       else {

           System.out.println("The result is " + (numerator/denominator));

       }

       

   }

   

}

<h2>Explanation:</h2>

// import the Scanner class to allow for user input

import java.util.Scanner;

// 1. Declare a class

public class FractionToDecimal {

   // 2. Write the main method

   public static void main(String[] args) {

       

       // 3. Create an object of the Scanner class called <em>input</em>

       Scanner input = new Scanner(System.in);

       

       // 4. Prompt the user to supply the numerator

       System.out.println("Please enter the numerator");

       

       // 5. Declare and initialize a variable <em>numerator </em>to hold the numerator

       // supplied by the user.

       // The numerator is of type double since the program does not

       // specify any. With a double both integer and floating point numbers

       // will be supported.

       double numerator = input.nextDouble();

       

       // 6. Prompt the user to enter the denominator

       System.out.println("Please enter the denominator");

       // 7. Declare and initialize a variable <em>denominator </em>to hold the

       // denominator supplied by the user.

       // The denominator is also of type double since the program does not

       // specify any. With a double, both integer and floating point numbers

       // will be supported.

       double denominator = input.nextDouble();

       // 8. Check if the denominator is or is not zero.

       // if it is zero, display an error message        

       if(denominator == 0){

           System.err.println("ERROR - Cannot divide by zero.");

       }

       // if it is not zero, then print out the result of the division

       else {

           System.out.println("The result is " + (numerator/denominator));

       }

       

   }                       // end of main method

   

}                            // end of class declaration

Please Note:

The code above has been written in Java.

The explanation segment contains comments to explain every line of the code.

But a few things are still worth noting;

i. Dividing the numerator by the denominator will convert a fraction to decimal.

ii. The object of the Scanner class <em>input </em> is used to get the inputs (numerator and denominator) from the user. Since the inputs are going to be integers or doubles, the nextDouble() method of the the Scanner class is used.

iii. If the denominator is zero, an error message will be displayed. I have used the System.err.println() method for that rather than the regular System.out.println() method. The difference is that the former will print out the error text in red color.

iv. Notice also that the else statement in the code will perform the division and also print out the result of the division along side with some text.

<em>Hope this helps!</em>

Why is it important to explore an Integrated
dezoksy [38]

Answer:

The answer to this question is given below in the explanation section. The correct answer is B.

Explanation:

The purpose behind to explore an integrated development environment is to learn more about the features of the environment.

So the correct answer is B.

For example, you can use visual studio to build asp.net application using c#, then you need to explore what features visual studio offering to you.

However, other options are incorrect. Because, you can learn more about syntax, error handling, and abstraction in the programming language, not in the IDE.
