Why does this not work The image displays an error message output commonly seen in programming environments. Below is a transcription of the text that would be typical for an educational setting:---**Java Compiler Error Example: Understanding "Cannot Find Symbol"**In this example, we observe a common compilation error that occurs when the Java compiler cannot find a referenced variable or method. This typically happens when the variable is either not declared or out of scope. Here is a breakdown of the error output:```MyProgram.java:20: error: cannot find symbolif (rsvp = true && number == 1) { ^ symbol: variable number location: class MyProgramMyProgram.java:23: error: cannot find symbolelse if (rsvp = true && number == 2) { ^ symbol: variable number location: class MyProgramMyProgram.java:26: error: cannot find symbolelse if (rsvp = true && number == 3) { ^ symbol: variable number location: class MyProgram```**Key Points:**1. **Error Type**: `cannot find symbol` - This indicates that the compiler cannot resolve a reference to a variable or method. 2. **Mistake in the Code**: - The variable `number` is not recognized in the context it's being used. This could be due to it not being declared before use or not being in the scope of the method or class.3. **Lines with Errors**: - The errors occur on lines 20, 23, and 26, where the code attempts to evaluate a condition involving `number`.4. **Probable Causes**: - The variable `number` might not have been declared in the class `MyProgram`. - It might be a case of a typo or incorrect variable name.**Resolution Tips**:- Check if the variable `number` has been declared appropriately within the class or method.- Ensure correct spelling and capitalization as Java is case-sensitive.- Consider the scope of variable `number`; it should be accessible within the class `MyProgram`.Understanding and fixing such compilation errors is essential for efficient Java programming and debugging.--- This transcription and explanation provide a foundational understanding of the "cannot find symbol" error, helping learners effectively troubleshoot and resolve similar issues in their code. ```javaimport java.util.Scanner;public class MyProgram{ public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Answer true or false, Are you attending? "); boolean rsvp = sc.nextBoolean(); if(!rsvp) { System.out.println("Sorry you can't make it"); } if(rsvp == true){ System.out.println("Please enter a menu number: "); int number = sc.nextInt(); if(rsvp == true && number == 1) { System.out.println("Thanks for attending. You will be served beef."); } else if(rsvp == true && number == 2) { System.out.println("Thanks for attending. You will be served chicken."); } else if(rsvp == true && number == 3) { System.out.println("Thanks for attending. You will be served pasta."); } else { System.out.println("Thank you for attending. You will be served fish."); } } }}```### DescriptionThis Java program, named `MyProgram`, is designed to handle the attendance status and menu preference of a guest. It utilizes the `Scanner` class to accept user input. Here is an explanation of how the program operates:1. The program begins by outputting a prompt asking whether the user is attending: "Answer true or false, Are you attending?" This expects a boolean (true/false) input.2. If the response (`rsvp`) is `false`, the program will respond with "Sorry you can't make it" and terminate further operations.3. If `rsvp` is `true`, the user is prompted to enter a menu number: "Please enter a menu number:".4. Depending on the number entered (1, 2, or 3), a corresponding message is printed: - Number 1: "Thanks for attending. You will be served beef." - Number 2: "Thanks for attending. You will be served chicken." - Number 3: "Thanks for attending. You will be served pasta." 5. If a different number is entered, the program defaults to: "Thank you for attending. You will be served fish."This simple program encodes conditional logic to manage event attendance and meal selection based on user input.
