Objects & Object References
Objects & Object References
Declaring objects:
Counter a = new Counter(0);
Counter b = new Counter(1);
Method invocation:
a.increment();
b.decrement();
Testing for equality:
a == b //simply tests if a and b reference the same object
a.equals(b) //tests object equality - using default Object method
Automatic garbage Collection:
a = b; //cause the object referenced by a to be garbage collected,
a = null; //there is no explicit deallocation of storage.
