Answer #1

What are the legal array index values?
Legal index values are 0 to size-1. if size is 5 than legal indexes are 0,1,2,3,4

What is a bounds error?
If we try to access any illegal index in the array than we will get bound error

What is an instance method, and how does it differ from a static method?
instance methods are object methods which requires object to invoke at.. they are availale for each object as differetncopy
static methods are class level methods these are common to all objects and these methods can be called using class name

How many constructors can a class have?
class can have any number of constructors
Can you have a class with no constructors?
yes we can write but compiler will add the default constructor to it
If a class has more than one constructor, which of them gets called?
It depends on the arguments your passing while creating the object

How to use C++ figure this question? Collection and Sorted Collection An array is great for storing a list of values. However, one challenge when working with arrays is they have a fixed size. If you declare an array of size 10 and later need to actually store 11 elements you have to create a new array and copy everything over. C++ (and other langauges) create classes that handle this and other operations behind the scenes. In this assignment, we...

You are asked to implement a C++ class to model a sorted array of unsigned integers. The class is to be used in an embedded application that cannot assume the presence of the STL. The array has to be dynamically allocated in such a way that allows programmers using it to specify the required size. Your class should should: (1) provide the appropriate constructors and destructor; (2) provide methods for updating, and showing numbers in/to the array (e.g., to be...

Write the Game class, Java lanuage. A Game instance is described by three instance variables: gameName (a String), numSold (an integer that represents the number of that type of game sold), and priceEach (a double that is the price of each of that type of Game). I only want three instance variables!! The class should have the following methods: A constructor that has two parameter – a String containing the name of the Game and a double containing its price....

Given a class: public class Money { int wholeNumber; int decimalPart; boolean positive; char currencySymbol; } Write a constructor for setting the 4 instance variables (in the order specified above). The constructor must validate the input throwing an IllegalArgumentException (you can specify any error message you see fit) if any of the following conditions are not met: either the int values are negative decimalPart is greater than 99 the currencySymbol is not one of '$', '€', or '£' Write an...

Write a Java class called Grades in a class file called Grades.java. 2. Grades reads from a text file containing a series of course grades (a value between 0.0 and 100.0) with one grade entry per line. However, the first line in the file is an integer value specifying how many grade entries are contained in the file. 3. The Grades class contains four static methods: a. A method called loadGrades() that opens the file, reads in the data and...
