Your program must have these methods: • main - This method will be in your main class. Handle all user interaction, call processFile and pass user input as arguments • CaesarEncode - This method must be in the caesar class as provided in the .java file above • Caesar Decode - This method must be in the caesar class as provided in the .java file above • processFile - This method can be in the main class or another custom class, but do not put it in the caesar class. The processFile method must have a minimum of three parameters - one for each user input including inputFileName, outputFileName, encodeDecode (see Important Note at the bottom of this page). This method will read the file using the inputFileName file, call the CaesarEncode or Caesar Decode function depending on the encodeDecode argument and write to the outputFileName file. Important Note: this method will be performing file input/output operations. You are required to properly handle the FileNotFoundException Your main function should: 0. Display a greeting and ask if the the user would like to encode or decode a message. 1. Prompt for inputFileName, the name of the input file. 2. Prompt for outputFileName, the name of the output file. 3. call processFile and pass the user's input as arguments. Your processFile method should: 1. Use the following heading including a minimum of three parameters (see important note below): bool processFile(String inputFileName, String outputFileName, String encodeDecode) 2. Use the inputFileName parameter as the name of the input file. 3. Use the outputFileName parameter as the name of the output file. 4. Try to open the input file. Catch any FileNotFoundException. 5. Loop through the following steps: a. read a character from the input file. b. if end-of-file was reached, then terminate repetition. c. if the encodeDecode parameter is equal to "encode", call the CaesarEncode function or if the encodeDecode parameter is equal to "decode" call the CaesarDecode function d. write the encoded or decoded character to the output file. Catch any FileNotFoundException. End loop. 6. Return true Important Note: The CaesarEncode and Caesar Decode methods require a key. You can choose whether to ask the user for the key in the main method (remember: all user interaction will happen in the main method). If you ask the user for the key, modify the processFile heading to include a parameter for the key and pass the user's key when you call а processFile. If you decide not to ask the user for the key, you can hard code the key into the processFile method so it will use the same key everytime. Either way is fine. public class caesar /****** * CaesarEncode implements the Caesar cipher encoding scheme. Receive: ch, a character. key, the amount by which to rotate ch.

The following description is incorrect:

TLS provides protection against SQL injection attacks.

TLS (Transport Layer Security) and SSL (Secure Sockets Layer) are cryptographic protocols designed to secure communication over a network. They provide encryption, data integrity, and authentication for various applications, including HTTPS (HTTP over TLS/SSL).

However, TLS/SSL does not directly protect against SQL injection attacks. SQL injection is a vulnerability that occurs in web applications when malicious SQL statements are inserted into an entry field, leading to unauthorized access or manipulation of data in the database.

Preventing SQL injection attacks requires proper input validation, parameterized queries, and other secure coding practices at the application level. While TLS/SSL can help protect the confidentiality and integrity of data during transmission, it does not address the specific vulnerability of SQL injection.

The address in direct mapping is divided into three fields: the tag, line, and word.

The tag field contains the high-order bits, the line field contains the middle-order bits, and the word field contains the low-order bits.  

The number of bits that each field contains is calculated using the formulas.

To compute the number of bits required for each field, we need to first find the number of bits needed to represent each field.

For Associative Mapping:

In associative mapping, the tag field of the address is compared to the tag fields of all lines in the cache.

If a match is found, then the corresponding line is used to access the block.

Since there is no explicit line number in the address, we cannot determine which line in the cache is allocated to the block containing this Byte. Instead, we have to search all lines in the cache to find a match for the tag.

If we find a match, then the corresponding line is used to access the block If another block with the same line number is loaded into the cache, the existing block is replaced.

In associative mapping, each block of main memory can be mapped to any line in the cache.

3. Unique room layout: Sometimes, the shape and layout of a room may require you to adjust the furniture spacing to fit the space properly.

4. Multifunctional spaces: If a room serves multiple purposes, such as a living room that also serves as a home office, you may need to modify the furniture placement to accommodate the different functions.

Regardless of the situation, it's crucial to ensure that the furniture arrangement still provides a comfortable and functional space.

The is Heap() method can be implemented to check whether the current heap is a valid min-heap. The isHeap() method must be added to the Heap class that will check if the current heap is a valid min-heap.

This method should be implemented as follows:public boolean isHeap() {for (int i = 0; i < data.size(); i++) {int leftChild = childPosition(i, 0);int rightChild = childPosition(i, 1);if (leftChild < data.size() && data.get(leftChild) < data.get(i)) {return false;}if (rightChild < data.size() && data.get(rightChild) < data.get(i)) {return false;}return true;}

In this method, we loop through each node of the heap and compare the values of the left and right children to that of the parent. If the value of either of the child nodes is smaller than the value of the parent node, it is not a valid min-heap, so we return false.

       Course course2 = new Course("Science");

       Course course3 = new Course("English");

       student1.addCourse(course1);

       student1.addCourse(course2);

       student2.addCourse(course2);

       student2.addCourse(course3);

       student3.addCourse(course1);

       student3.addCourse(course3);

       ArrayList<Student> students = new ArrayList<>();

       students.add(student1);

       for (Student student : students) {

           student.displayCourses();

           System.out.println();
