The default constructor initializes method variables.

The default constructor has the same access as its class.

The default constructor invoked the no-arg constructor of the superclass.

If a class lacks a no-arg constructor, the compiler always creates a default constructor.

The compiler creates a default constructor only when there are no other constructors for the class.

int[] scores = {3, 5, 7};

int [][] scores = {2,7,6}, {9,3,45};

String cats[] = {“Fluffy”, “Spot”, “Zeus”};

boolean results[] = new boolean [3] {true, false, true};

Explicitly setting myA to null marks that instance to be eligible for garbage collection

Private instances of A become eligible for garbage collection when instances of Alpha become eligible for garbage collection.

Any call on tryIt() causes the private instance of A to be marked for garbage collection.

There are no instanced of A that will become eligible for garbage collection.

Implementation details of the class are hidden.

Access modifiers can be omitted on class data members.

Internal operation of the class can be modified without impacting clients of that class.

Code that uses the encapsulation class can access data members directly.

Performance of class methods is improved.

k will display garbage values

k will print 0, as default constructor is called.

Error as no constructor is defined.

Error, as main should precede with int and should return 0.
