Chapter 10
All classes directly or indirectly inherit from this class
Object
When a method is declared with the "final" modifier, it must be overriden in a subclass
false
An anonymous inner class must
implement an interface
You use the ___ operator to define an anonymous inner class
new
A functional interface is an interface with
only one abstract method
A method in a subclass having the same name as a method in the superclass but a different signature is an example of
overloading
Abstract methods must be
overridden
A method in a subclass that has the same signature as a method in the superclass is an example of
overriding
A subclass does not have access to these superclass members
private
these superclass members are accessible to subclasses and classes in the same package
protected
When a class implements an interface, it must
provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified
in an inheritance relationship, this is the specialized class
subclass
The following is an inexplicit call to the supercalss's default constructor
super()
in an inheritance relationship, this is the general class
superclass
A superclass has a member with package access. A class that is outside the superclass's package but inherits from the superclass can access the member
true
A superclass reference variable can reference an object of a subclass that extends the superclass
true
By default all members of an interface are public
true
In a subclass, a call to the superclass constructor can only be written in the subclass constructor
true
The superclass constructor always executes before the subclass constructor
true
When a class contains an abstract method, the class cannot be instantiated
true
In a subclass constructor, a call to the superclass constructor must
appeat as the very first statement
You can use a lambda expression to instantiate an object that
implements a functional interface
This operator can be used to determine whether a reference variable references an object of a particular class
instance of
this key word refers to an object's superclass
base
Abstract classes cannot
be instantiated
Fields in an interface are
both final and static
With this type of binding, the Java Virtual Machine determines at runtime which method to call, depending on the type of the object that a variable references
dynamic
this key word indicates that a class inherits from another class
extends
A class may only implement one interface
false
A subclass reference variable can reference an object of the superclass
false
An object of a superclass can access members declared in a subclass
false
Constructors are not inherited
false
If a subclass constructor does not explicitly call a superclass constructor, Java will not call any of the superclass's constructors
false
