Expert Solution & Answer
Chapter 4, Problem 2RQ
Explanation of Solution
Lexical analysis and syntax analysis:
Syntax analyzer phase in compilation process is the step in which the “tokens” in the programs are identified and recognize whether they are specified in a valid way. In simple words, tokens are the keywords, identifiers and operators in a
- Lexical analysis: It does the analysis of small language constructs like names and numeric literals.
- Syntax analysis: It does the analysis of large constructs like expressions and program units.
The following three reasons explain why lexical analysis is a separate part from the syntax analyzing process.
Simplicity:
The process of lexical analysis needs relatively less complex techniques than syntax analysis. So, separating low-level details of lexical analysis from syntax analysis make the process of lexical analysis simple, small and clean...

Please answer JAVA OOP problem below:
You are working at a university that tracks students. Each student is identified by their name and faculty advisor. Each faculty advisor is identified by their name, department, and maximum number of students they can advise.
Using solid OO design principles, create a modular program that implements all the classes for the problem and also creates an implementation class that gathers user input for one student and then prints out the information gathered by creating the appropriate data definition and implementation classes. All data must be validated.
I have given the code so far:
Implementation:
import javax.swing.JOptionPane;
public class Implementation {
public static void main(String[] args) {
FacultyAdvisor facultyAdvisor = new FacultyAdvisor("Sharmin Sultana", "IT", 30);
Student student = new Student("John", facultyAdvisor);
JOptionPane.showMessageDialog(null, student.toString());
}
}
