Encapsulation is a form of data hiding.

A tightly encapsulated class is always immutable.

Encapsulation is always used to make programs run faster.

Encapsulation helps to protect data from corruption.

Encapsulation allows for changes to the internal design of a class while the public interface remains unchanged.

A top-level class can not be called "tightly encapsulated" unless it is declared private.

Encapsulation enhances the maintainability of the code.

A tightly encapsulated class allows fast public access to member fields.

A tightly encapsulated class allows access to data only through accessor and mutator methods.

Encapsulation usually reduces the size of the code.

A tightly encapsulated class might have mutator methods that validate data before it is loaded into the internal data model.

The class is declared final.

All local variables are declared private.

All method parameters are declared final.

No method returns a reference to any object that is referenced by an internal data member.

With assertions enabled it prints 210210-1 followed by an AssertionError message.

With assertions enabled it prints ABC followed by an AssertionError message.

With assertions disabled it prints ABC followed by an AssertionError message.

Assertions should not be used within the default case of a switch statement.

In this code example a throw statement must be used in place of the assert statement.

Compile-time error

If assertions are not enabled at run time it prints an error message.

If assertions are not enabled at run time it prints nothing.

With assertions enabled it prints an error message.

With assertions enabled it prints nothing.

The assert statement is being used to check a class invariant--something that must be true about each instance of the class

The assert statements are being used to check a precondition--something that must be true when the method is invoked.
