Explanation of Solution

XML - Extensible Markup Language

  • XML is a language that contains a collection of rules used for encoding the content of a document in a format (human-readable and machine-readable).
  • It is used to carry the content of any document.
  • The tags are not predefined; and so the programmers can create their own set of tags to describe the data used in the document.
  • The elements should have the start tag and its matching end-tag.
  • XML is a metalanguage which was established by World Wide Web Consortium.
  • It is an extended version of SGML (Standard Generalized Markup Language) that is used to describe more markup languages.
  • The DTD describes the structure of a particular XML document.
    • The Document Type Definition (DTD) is an organization specification of an XML document.
  • The filename extension is “...

2. UNIX Shell and History Feature [20 points] This question consists of designing a C program to serve as a shell interface that accepts user commands and then executes each command in a separate process. A shell interface gives the user a prompt, after which the next command is entered. The example below illustrates the prompt osh> and the user's next command: cat prog.c. The UNIX/Linux cat command displays the contents of the file prog.c on the terminal using the UNIX/Linux cat command and your program needs to do the same. osh> cat prog.c The above can be achieved by running your shell interface as a parent process. Every time a command is entered, you create a child process by using fork(), which then executes the user's command using one of the system calls in the exec() family (as described in Chapter 3). A C program that provides the general operations of a command-line shell can be seen below. #include #include #define MAX LINE 80 /* The maximum length command */ { int…
Question#2: Design and implement a Java program using Abstract Factory and Singleton design patterns. The program displays date and time in one of the following two formats: Format 1: Date: MM/DD/YYYY Time: HH:MM:SS Format 2: Date: DD-MM-YYYY Time: SS,MM,HH The following is how the program works. In the beginning, the program asks the user what display format that she wants. Then the program continuously asks the user to give one of the following commands, and performs the corresponding task. Note that the program gets the current date and time from the system clock (use the appropriate Java date and time operations for this). 'd' display current date 't': display current time 'q': quit the program. • In the program, there should be 2 product hierarchies: "DateObject” and “TimeObject”. Each hierarchy should have format and format2 described above. • Implement the factories as singletons. • Run your code and attach screenshots of the results. • Draw a UML class diagram for the program.
