Required Task: Implement a chat system that consists of two processes (Pland P3). The two processes communicate with each other via shared memory. This system works as follows: ✓ P1 takes a string as a command line argument and writs it to the shared memory. ✓P3 reads the shared memory contents, converts it to upper case, and writes it to the terminal.

Compliant/Noncompliant Solutions The following code segment was provided in Secure Coding Guidelines for Java SE: void readData() throws IOException{ BufferedReader br = new BufferedReader(new InputStreamReader( new FileInputStream("file"))); // Read from the file String data = br.readLine();} The code is presented as a noncompliant coding example. For this assignment, identify two compliant solutions that can be utilized to ensure the protection of sensitive data. Provide a detailed explanation of factors, which influence noncompliant code and specifically how your solutions are now compliant. Your explanation should be 2-3 pages in length. Submit the following components: Word document with appropriate program analysis for your compliant solutions and source code in the Word file. Submit your .java source code file(s). If more than 1 file, submit a zip file.
If wrong answer this time will downvote it Create a class with a static main that tests the ability to resolve and print a Path: • Create an instance of a FileSystem class. • Resolve an instance of a Path interface from a directory path and filename. • Print the constructed Path with System.out.println() method. 2. Create a class with a static main that tests the ability to resolve and print a Path: • Create an array of Path class. • Instantiate instances of Path with absolute and relative paths. • Print the constructed elements of the array of Path class with System.out.println() method. 3.

Scenario: You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.
Challenge 3: Encryption.java and Decryption.java Write an Encryption class that encrypts the contents of a binary file. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded content out to a second file. The second file will be a version of the first file, but written in a secret code. Use a simple encryption technique, such as reading one character at a time, and add 10 to the character code of each character before it is written to the second file. Come up with your own encryption method. Also write a Decryption class that reads the file produced by the Encryption program. The decryption file will use the method that you used and restore the data to its original state, and write it to a new file.
