    In Java, aggregation and composition are two forms of association that describe relationships between classes. Both represent a "has-a" relationship, but they differ in the strength of the relationship and the lifecycle dependency of the contained objects.

    Aggregation

    Aggregation is a weaker form of association where one class (the whole) contains a collection of other classes (the parts). However, the lifecycle of the parts does not depend on the whole. This means that the contained objects can exist independently of the container object. For example, a library and books show aggregation, as books can exist independently of the library1.

    Example

    // Java program to illustrate the concept of Aggregation
    import java.util.*;

    class Student {
    private String studentName;
    private int studentId;

    public Student(String studentName, int studentId) {
    this.studentName = studentName;
    this.studentId = studentId;
    }

    public String getStudentName() {
    return studentName;
    }

    public int getStudentId() {
    return studentId;
    }
    }

    class Department {
    private String deptName;
    private List<Student> students;

    public Department(String deptName, List<Student> students) {
    this.deptName = deptName;
    this.students = students;
    }

    public List<Student> getStudents() {
    return students;
    }
    }

    class Institute {
    private String instituteName;
    private List<Department> departments;

    public Institute(String instituteName, List<Department> departments) {
    this.instituteName = instituteName;
    this.departments = departments;
    }

    public int getTotalStudentsInInstitute() {
    int noOfStudents = 0;
    for (Department dept : departments) {
    noOfStudents += dept.getStudents().size();
    }
    return noOfStudents;
    }
    }

    public class AggregationExample {
    public static void main(String[] args) {
    Student s1 = new Student("Parul", 1);
    Student s2 = new Student("Sachin", 2);
    List<Student> cse_students = new ArrayList<>();
    cse_students.add(s1);
    cse_students.add(s2);

    Department CSE = new Department("CSE", cse_students);
    List<Department> departments = new ArrayList<>();
    departments.add(CSE);

    Institute institute = new Institute("BITS", departments);
    System.out.println("Total students in institute: " + institute.getTotalStudentsInInstitute());
    }
    }
