Answered: JAVA code can only be added to the MessageDetails.java file. Between lines of get code (ie libnes 12 and 14, as seen on image).

Transcribed Image Text:**Overview of Java Code for Message Handling** The provided Java code demonstrates how to utilize mutator and accessor methods within a class to manage simple message data. The `Message` class includes fields and methods to handle a greeting message and a corresponding area code. **Class and Methods Description:** 1. **Class Definition:** ```java public class Message { ``` The class is defined as `Message` and includes private fields for encapsulating data. 2. **Fields:** ```java private String greeting; private int areaCode; ``` - `greeting`: Stores the greeting message as a `String`. - `areaCode`: Stores the area code as an `int`. 3. **Mutator Methods:** - **setGreeting Method:** ```java public void setGreeting(String inputGreeting) { greeting = "Hi, you have reached " + inputGreeting; } ``` This method sets the `greeting` field by appending the input string to a predefined message. - **setAreaCode Method:** ```java public void setAreaCode(int inputAreaCode) { areaCode = inputAreaCode; } ``` This method assigns the input integer to the `areaCode` field. 4. **Accessor Methods:** - **getGreeting Method:** ```java public String getGreeting() { return greeting; } ``` Returns the current greeting message. - **getAreaCode Method:** ```java public int getAreaCode() { return areaCode; } ``` Returns the current area code. **Usage Example:** When `setGreeting("Dan")` and `setAreaCode(464)` are executed, the output will be: ``` Voicemail: Hi, you have reached Dan at area code 464 ``` **Diagram Explanation:** The image provides a clear view of the code structure with interactive buttons labeled `MessageDetails.java` and `Message.java`, indicating separate Java files for organization and modularity in larger applications.

Transcribed Image Text:### Explanation of Code Snippet for Educational Purposes #### Overview The Java program consists of a class named `MessageDetails` that takes input for a greeting and an area code, and then prints a formatted voicemail message using these inputs. #### Description - **Classes and Methods**: - The program imports the `Scanner` class for taking user input. - The `MessageDetails` class contains the `main` method where the execution starts. - An instance of the `Message` class is created, though the details of this class are not provided in the snippet. - **Functionality**: - The program first initializes a `Scanner` object to read input data. - It then creates a `Message` object named `voicemail`. - Two variables, `inputGreeting` and `inputAreaCode`, are used to store the user's input for the greeting and area code, respectively. - The `inputGreeting` is read using `scnr.next()`, capturing a single word of input. - The `inputAreaCode` is read using `scnr.nextInt()`, capturing a numerical value. - **Code to Insert**: - The placeholder `/* Your code goes here */` suggests that additional instructions are needed, likely involving calling the `setGreeting()` and `setAreaCode()` methods on the `voicemail` object to set these values. - **Output**: - The program outputs the formatted voicemail message: ``` Voicemail: Hi, you have reached [Name] at area code [Code] ``` #### Example If the input is `Dan 464`, the output will be: ``` Voicemail: Hi, you have reached Dan at area code 464 ``` This program illustrates object-oriented principles in Java, showcasing how to manipulate class fields and methods to format strings based on user input.
