A server’s data requirements and the implementation of its methods are hidden from the client. This approach is referred to as ____.

An object has ____ as defined by the methods of its class.

The combining of data and behavior into a single software package is called ____.

At the root (base) of Java’s class hierarchy is a class called ____.

Constructors are activated when the keyword ____ is used.

____ variables can be declared in a method to provide temporary working storage for data in the method.

Which of the following represents the general form of a method?

The ____ of a variable is the period during which it can be used.

If a method has a return type, its implementing code must have at least one ____ statement that returns a value of that type.

Suppose a Student class contains a method setName to set the value of a Student object’s instance variable name, plus a method getName to access the value of name. Consider the following code fragment:

Student s1, s2;
s1 = new Student();
s2 = new Student();
s1.setName(“Bill”);
s2.setName(“Eric”);
s2 = s1;
s2.setName(“Bob”);
System.out.println( s1.getName() );

What would be displayed on the console?

The scope of a ____ is all the methods in the defining class.

Messages that change an object’s state are called ____.

Methods used to initialize a new object are called ____.

Class definitions usually begin with the keyword ____, indicating that the class is accessible to all potential clients.

Because unreferenced objects cannot be used, Java deletes them during a process called ____________________.

The visibility modifier ____________________ should be used when you want a method to be available to clients of the defining class.

An object has a(n) ____________________, which is another way of saying that at any particular moment its instance variables have particular values.

A(n) ____________________ is a software package or template that describes the characteristics of similar objects.

The ____________________ of a variable is that region of the program within which it can validly appear in lines of code.

An object is an instance of its class, and the process of creating a new object is called ____________________.

A client’s interactions with a(n) ____________________ are limited to sending it messages.

The keywords private and public are ____________________ modifiers.

At any time, it is possible to break the connection between a variable and the object it references by assigning the value ____________________ to the variable.

When a program attempts to run a method with an object that is null, Java throws a(n) ____________________.

If the return type of a method is not void, it can be any primitive or reference type.

A reference variable can be compared to the null value.

You should use local variables to remember information in an object.

Instance variables are nearly always declared to be public.

Class names must adhere to the rules for naming variables and methods.

You cannot have a local variable and a global variable with the same name in a class.

Memory for an object’s data is stored as part of the class template.

A client needs to know only a server’s interface.

Every object has its own unique identity.

Helper methods are usually public.

You cannot call one constructor from another constructor.

Method names have the same syntax as other Java identifiers.

When an object is instantiated, it gets a complete set of fresh instance variables

It is not possible for two variables to refer to the same object.

If a class template contains no constructors, the JVM provides a primitive default constructor.
