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!
Examples
