[SOLVED] Java program that simulates the actions of a preprocessor

Image
By
In most programming languages, the compiler carries a preprocessing step to determine if certain statements will compile. For instance, it may check to see if parentheses match.
Write a Java program that simulates the actions of a preprocessor, to detect if certain Java constructs are syntactically correct. Table 1 shows the types of Java statement formats under consideration, and also an example of each statement.


Note: In your implementation, design a class called Preprocessor that accepts a file that represents the program to be analyzed. The class will contain, among other possible methods, a method that determines whether or not the statement in the file are valid, with respect to the delimiters of Table 2. Do not be concerned with other symbols.

  1. You will need a test class. You may want to name it MyPreprocessor.
  2. You may have to enter all statements on a single line unless you will be reading the input from a file, in which case the file would be read using presumably the class BufferedReader or LineNumberReader.
  3. Your output would echo the input, and say whether or not the input passed the preprocessing stage.
  4. You are to use the concept of the stack to determine if the constructs are syntactically correct.

Zoo Management System - Project Details: You are the employee of a big, worldwide working Zoo Management Company. Your company is responsible for the Zoo management. Your boss thinks it would be a great idea to store all data for each Zoo in a brand new self-developed ZOO Management System. Up to now, the ZOO management company has maps of each ZOO available. Your boss knows that you took a course in introduction on an ERP system, so he asks you if you could help designing such a system. Each ZOO must have the same organizational structure, which should look like this: Each Zoo has a Zoo-Address. Each Zoo has many visitors (Visitor Ticket Process (VTP). Many Zoo-Attractions belong to a Zoo. Module 1: Entity Relationship Diagram Design a ER (entity-relationship) diagram for your ZOO Management System. Use the information provided below with the entities and its attributes. Put the entities in the correct relationship to each other (organizational structure). Module 2: DB Implem...

Sudoku Game Project in Java with full source code including GUI task

By
Introduction The purpose of the project is to try in practice the use of recursion and object-oriented program design. Please make sure to read this entire note before starting your work. Pay close attention to the sections on deadlines, deliverables, and exam rules. The problem Your task in this part of the project is to write a solver for Sudoku puzzles. Sudoku puzzles are a kind of crossword puzzles with numbers where the following two conditions have to be met: In each row or column, the nine numbers have to be from the set [1,2,3,4,5,6,7,8,9] and they must all be different.  For each of the nine non-overlapping 3x3 blocks, the nine numbers have to be from the set [1,2,3,4,5,6,7,8,9] and they ust all be different. The following two figures show a Sudoku puzzle and its solution. The input The input of your program, the Sudoku puzzles, is given in text files. More specifically, they are represented as nine lines of nine characters separated by spaces. The characters can be of two...
