You cannot use the isinstance function to determine whether an object is an instance of a subclass of a class.(T/F)

True or False 1) After a user defines his/her own constructor in a Java class, the default constructor is still available. ​___(2) Java supports multiple inheritances directly. ​___(3) Some methods in an interface can have method body.

(Java) The Sculpture Subclass Write class as follows: The class is named Sculpture, and it inherits from the Painting class. It has a private boolean member variable named humanForm It has a default constructor that assigns the values "No name" to name, "No artist" to artist, -1 to the year, "No medium" to the medium, and false to the humanForm variable. This default constructor calls the five argument constructor. It has a five-argument constructor to assign values to the name, artist, year, medium, and humanForm variables. It has a getter and setter for the humanForm variable. It has a toString() method. This class contains no other methods Make sure to include your name, the name of this class, our course number, and the Activity number in a Javadoc comment at the top. Make sure to write a Javadoc comment for each of these methods.

Describe the access modifiers that you can use for the members of a class

In order to do a range of tasks, both code and forms employ the ACTION and METHOD attributes.

C++ Assignment---This is an unfinished code please complete it. Make changes if necessary. Upvote for finished working code. Objectives • To apply knowledge of classes and objects Instructions Implement all of the following, each in a separate Visual Studio project (and/or solution). 1. Define a class called CounterType to implement a simple counter. The class must have a private field (data member) counter of type int. You must also provide methods (member functions), including the following: a. A constructor to set the counter to the value specified by the user b. A constructor to set the counter to 0 c. A method to allow the user to set the counter to a value they specify d. A method to increment the counter by 1 e. A method to decrement the counter by 1 Your code must ensure the value of counter is never negative. If the user calls a method to attempt to make the counter negative, set the counter to 0 and print out an error to the user (e.g., “The counter must not be negative.”) Do…

What are the three things that you are required to perform for classes that include member variables that are pointers?

functions return the value of a data member. A. Accessor OB. Member C. Mutator OD. Utility

Using C# language: Programming PLO-2 Measured: Design, implement, and evaluate computer solutions utilizing structured and object-oriented programming methodologies.   Design a class named Contractor. The class should keep the following information:   Contractor name Contractor number Contractor start date   Write one or more constructors and the appropriate accessor and mutator functions for the class.
