Three accessor methods, `getSender()`, `getReceiver()`, and `getMessage()`, were added to the `TextMessage` class. These methods allow retrieval of the values stored in the private variables `sender`, `receiver`, and `message`. They can be used to access and utilize these values in other parts of thecode.In the given code, you are asked to add three accessor methods to the `TextMessage` class. Accessor methods are used to retrieve the values of private instance variables in aclass.To complete this task, follow these steps:1. Open the `TextMessage.java` file.2. Add the following method to the `TextMessage` class:- `public String getSender()`: This method will return thevalueof the `sender` variable.3. Add another method:- `public String getReceiver()`: This method will return the value of the `receiver` variable.4. Finally, add the last method:- `public String getMessage()`: This method will return the value of the `message` variable.Here's an example of how the code should look after adding the accessor methods:```javapublic class TextMessage {private String message;private String sender;private String receiver;public TextMessage(String from, String to, String theMessage) {sender = from;receiver = to;message = theMessage;}public String getSender() {return sender;}public String getReceiver() {return receiver;}public String getMessage() {return message;}public String toString() {return sender + " texted " + receiver + ". " + message;}}```After adding the accessormethods, you can use them to retrieve the values of the private variables `sender`, `receiver`, and `message` in other parts of your code.For more such questionscode,Click onbrainly.com/question/28488509#SPJ8...
