Objects are to classes as __________ are to _______________.
A) variables … primitive data types
B) characters … strings
C) integers … numbers
D) squares … cubes
The correct option is :
A) variables ... primitive data types
Explanation : The primitive data types determine the type of data that can be stored in the variables. Similarly the object also exhibits the properties and behavior of its class.

Java. For C through H True or false? c. Primitive variables must be objects. d. Integer x; generates a compile time error. e. Integer y = new Integer(); generates a compile time error. f. Integer z = new Integer(3); generates a compile time error. g. Integer u = new Integer(3.14); generates a compile time error. h. Integer w = new Integer("345"); generates a compile time error. 1.) What is true of classes that can be used with the enhanced for...

classes. If we want to store primitive data types in an ArrayList object, then we should use accessor mutator static wrapper QUESTION 10 What is the purpose of this code? for (int i = 0; i < arrayName.length; i++ X for (int j - 0) < arrayNamelij length; j++ X Il process element arrayName[001 ) - it is the general pattern for processing the elements of a two-dimensional array called arrayName in column- first row second order It is...
Looking for some quick and useful notes on this: • Using Classes and Objects o Creating Objects: understand how to create objects, assign them, invoke methods on them and re-assign references. o The String Class: understanding and using strings and String methods o Packages: use import statement when needed o Wrapper Classes: use Wrapper classes to parse strings. • Writing classes o Anatomy of a Class: understand the concept of a class, define its instance variables, constructor and methods. o...
C++ 1. Classes and ____ have the same relationship as data types and variables. 2. In the statement double Rectangle : : getArea ( ) , Rectangle is the name of the ____ and ' : : ' is called ____. 3. If you were writing the declaration of a class named Canine, what would you name the file it was stored in? ____ 4. In a class without constructors, a ____ is written during compilation. 5. ____ provides a...
JAVA :The following are descriptions of classes that you will create. Think of these as service providers. They provide a service to who ever want to use them. You will also write a TestClass with a main() method that fully exercises the classes that you create. To exercise a class, make some instances of the class, and call the methods of the class using these objects. Paste in the output from the test program that demonstrates your classes’ functionality. Testing...
What this Assignment Is About: Review on Java I topics, such as primitive data types, basic I/O, conditional and logical expressions, etc. Review on Java loops. Documentation Requirements to get full credits in Documentation The assignment number, your name, StudentID, Lecture number(time), and a class description need to be included at the top of each file/class. A description of each method is also needed. Some additional comments inside of methods (especially for a "main" method) to explain code that are...
The creators of C++ have created primitive data types to allow developers to store numbers of various size they expect most users will need. Such as short, int, double. In our case we want to expand on these primitive data types and allow users to store big numbers that can store up to 1,000 digits long. In order to do this, you will create a BigNumbers class that will use vectors from STL to store the digits. BigNumbers should have...
Big Numbers Library The creators of C++ have created primitive data types to allow developers to store numbers of various size they expect most users will need. Such as short, int, double. In our case we want to expand on these primitive data types and allow users to store big numbers that can store up to 1,000 digits long. In order to do this, you will create a BigNumbers class, using TDD, Test Driven Development, that will use vectors from...
What is a CRC card associated with? a. The functions of classes. b. The variables of classes. c. The association between classes. d. An entire class.
