• Composition is an Association

• Aggregation is an Association

• Composition is a strong Association (If life of contained object totally depends on container object it is called strong association)

• Aggregation is a week Association (If life of contained object doesn't depends on container object it is called week association)

Example:

class Contained { public void disp() { System.out.println("disp() of Contained A"); } } public class Container { private Contained c; //Composition Container() { c = new Contained(); } //Association public Contained getC() { return c; } public void setC(Contained c) { this.c = c; } public static void main(String[] args) { Container container = new Container(); Contained contained = new Contained(); container.setC(contained); } }

• Aggregation is an Association

• Composition is a strong Association (If the life of contained object totally depends on the container object, it is called strong association)

• Aggregation is a weak Association (If the life of contained object doesn't depends on the container object, it is called weak association)
