Organizing Data with Java

Schools have lots of data—students, grades, classes. Java makes it easy to organize and search this information.

What to Include

• Store student names, IDs, and grades.
• Add or remove students.
• Calculate average grades.

Example Structure

class Student {
  String name;
  int id;
  double grade;
}

Use an ArrayList<Student> to manage all students.

Why It Matters

This is how real school systems, libraries, and companies manage their data every day!
