Answer Posted / b venkat reddy
The "is a" relationship is expressed with inheritance and
"has a" relationship expressed with composition.
Both inheritance and composition allow u to place sub-objects inside your new class.Two main techniques to code reuse are inheritance and composition.
Ex.: IS A ===>> house IS A building
class House {
.....
}
class Building extends House{
......
}
Ex.:HAS A ===>> house HAS A bathroom
class House {
Bathroom b = new Bathroom();
}
