d

A constructor is a method that: a) returns an object of the class. b) never receives any arguments. c) with the name ClassName.constructor. d) performs initialization or setup operations.

c

A constructor: a) always accepts two arguments b) has return type of void c) has the same name as the class d) always has an access specifier of private

braces

After the header, the body of the method appears inside a set of: brackets, [] parentheses, () braces, {} double quotes, ""

t

An object can store data. True False

instance of a class

Another term for an object of a class is: access specifier instance of a class member method

methods

Class objects normally have ________ that perform useful operations on their data. fields instances methods relationships

d

Data hiding, which means that critical data stored inside the object is protected from code outside the object, is accomplished in Java by: a) using the public access specifier on the class methods b) using the private access specifier on the class methods c) using the private access specifier on the class definition d) using the private access specifier on the class fields

d

For the following code, which statement is NOT true? a) x is available to code that is written outside the Circle class. b) radius is not available to code written outside the Circle class. c) radius, x, y, and z are called members of the Circle class. d) z is available to code that is written outside the Circle class.

a

For the following code, which statement is NOT true? a) x is directly available to code that is written outside the Circle class through object of a Circle. b) radius is directly available to code written outside the Circle class through object of a Circle.. c) radius, x, and y are protected members of the Circle class. d) y is directly available to code that is written outside the Circle class through object of a Circle.

Java allows you to create objects of this class in the same way you would create primitive variables. Random String PrintWriter Scanner

a

Look at the following statement. import java.util.*; This is an example of: a) a wildcard import of all classes in java.util package b) an explicit import of only one class c) unconditional import or two required classes d) conditional import o only one class

b

Look at the following statement. import java.util.Scanner; This is an example of a) a wildcard import b) an explicit import c) unconditional import d) conditional import

instance methods

Methods that operate on an object's fields that are known also as instance variables are called: instance variables instance methods public methods private methods

t
