Question

You are going to write an object that takes a word (or short phrase) as an input for the Constructor and then will reverse the letters in the word.

The object to implement this is referred to as **ReverseWord** and consists of **only** the following public methods:

**public void setWord(String word)** - Sets the word to be processed.

**public String getWord()** - Returns the word that is set with **setWord**. Note that if this is called before setWord then an empty String is returned.

**public String getReversedWord()** - Returns the word set by setWord with the letters in reverse order. Note that if this is called *before* **setWord** then an empty string is returned.

Note that you **do not** implement a Constructor. We will simply use the default constructor that Java creates for us. Your **Program.java** should contain code to test your **ReverseWord** object. Load multiple values and check to make sure that the values match the expected values.

Requirements:

-  You must implement this manually using a loop. While there are Java capabilities that can do this in a single line of code, you may NOT use them. Even though this is less efficient, the objective is to apply the use of loops.

## Getting Started

Create the following files

1. Program.java

2. ReverseWord.java

**You'll have to add the proper Javadoc documentation** as well as the proper code to solve the problem. You will have to add instance variables, constants, method stubs, and code to get this class defined properly. Read the comments (and the problem) to understand what the problem is and how you will solve it.  

You will need to add test code to **Program.java** to test the **ReverseWord.java** source code.

Once you've written your code run the code by right clicking on **Program.java** in the file explorer and selecting **Run** from the context menu or using the debug tool from the **Activity Bar**. Examine the output. Does it do what you want? If not, how can you modify the code to do what you want?

## Testing Your Code

Your **Main.java** should contain code to test your **ReverseWord** object. Ask the user for a word and then output the original word and its reversed version. A sample run is shown below:

```

Input word to be reversed: catalog

Input word: catalog

Reversed word: golatac

```

Answer 1

The solution is provided below

ReverseWord.java

public class ReverseWord {
   String word;
   String reversedWord;
   public ReverseWord() {
       word="";
       reversedWord="";
   }
   public String getWord() {
       return word;
   }
   public void setWord(String word) {
       this.word = word;
   }
   public String getReversedWord() {
       if(word.compareTo("")==0)
               return "";
       else {
           reversedWord="";
           for(int i=0;i<word.length();i++)
               reversedWord=word.charAt(i)+reversedWord;
       }  
       return reversedWord;
   }
}

--------------------------------------------------------------------

Program.java

import java.util.Scanner;

public class Program {

   public static void main(String[] args) {
       ReverseWord test=new ReverseWord();
       System.out.println("Input word: "+test.getWord());
       System.out.println("Reversed word: "+test.getReversedWord());
       Scanner sc=new Scanner(System.in);
       System.out.print("Input word to be reversed:");
       String input=sc.nextLine();
       test.setWord(input);
       System.out.println("Input word: "+test.getWord());
       System.out.println("Reversed word: "+test.getReversedWord());
       System.out.print("Input word to be reversed:");
       input=sc.nextLine();
       test.setWord(input);
       System.out.println("Input word: "+test.getWord());
       System.out.println("Reversed word: "+test.getReversedWord());
       System.out.print("Input word to be reversed:");
       input=sc.nextLine();
       test.setWord(input);
       System.out.println("Input word: "+test.getWord());
       System.out.println("Reversed word: "+test.getReversedWord());

   }

}

I have attached the screenhot of the test.Observe words are reversed.First time called without setWord get empty string.
