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>

How has technology effected the way we communicate?
horsena [70]

Indeed it has.

Advancements in technology and changes in communication generally go hand in hand. Landlines displaced the telegraph and cell phones replaced landlines. The arrival of the internet opened new doors of personal communication. E-mails replaced postal mails and social media took the place of text messages.

Communication technology, such as mobile phones, email, text messaging, instant messaging and social networking have had a profound effect on nearly everyone's business and personal lives. While technology makes communications faster and easier, at times it can also be intrusive and misinterpreted.

Increased isolation, reduced social interaction and social skills, and increased human-to-machine interactions are all a result of an overuse of technology, which has created a wall between many people globally.

Technology has the ability to enhance daily living from appliances to mobile devices and computers, technology is everywhere. ... In the rise of digital communication, technology can actually help communication skills because it allows people to learn written communication to varying audiences.
