This exercise challenges students to bridge the gap between class structures and dynamic data storage by using Java ArrayList methods within a static context. Core Objective of the Exercise
Before diving into the specific methods, it's important to understand their practical value: 7.2.9 Teacher Class List Methods
import java.util.ArrayList; public class Student private String name; private int grade; // Static list to store all student objects private static ArrayList classList = new ArrayList (); public Student(String name, int grade) this.name = name; this.grade = grade; classList.add(this); // Returns the last student added to the list public static Student getLastStudent() return classList.get(classList.size() - 1); // Returns the total number of students public static int getClassSize() return classList.size(); public String toString() return this.name + " (" + this.grade + ")"; Use code with caution.
