Chapter 10, Problem 1CP

In the previous homework scenario problem below: You have been hired by TechCo to create and manage their employee training portal. Your first task is to develop a program that will create and track different training sessions in the portal. Each training session has the following properties: • A session ID (e.g., "TECH101", "TECH205") • A session title (e.g., "Machine learning", "Advanced Java Programming") • A total duration in hours (e.g., 5.0, 8.0) • Current number of participants (e.g., 25) Each session must have at least a session ID and a total duration and must met the following requirements: • The maximum participant for each session is 30. • The total duration of a session must not exceed 10 hours. • The current number of participants should never exceed the maximum number of participants. Design an object-oriented solution to create a data definition class(DDC) and an implementation class for the session object.  In the DDC, a session class must include: • Constructors to…

Send me the lexer and parser

Here is my code please draw a transition diagram and nfa on paper public class Lexer { private static final char EOF = 0; private static final int BUFFER_SIZE = 10; private Parser yyparser; // parent parser object private java.io.Reader reader; // input stream public int lineno; // line number public int column; // column // Double buffering implementation private char[] buffer1; private char[] buffer2; private boolean usingBuffer1; private int currentPos; private int bufferLength; private boolean endReached; // Keywords private static final String[] keywords = { "int", "print", "if", "else", "while", "void" }; public Lexer(java.io.Reader reader, Parser yyparser) throws Exception { this.reader = reader; this.yyparser = yyparser; this.lineno = 1; this.column = 0; // Initialize double buffering buffer1 = new char[BUFFER_SIZE]; buffer2 = new char[BUFFER_SIZE]; usingBuffer1 = true; currentPos = 0; bufferLength = 0; endReached = false; // Initial buffer fill fillBuffer(); } private…
