a. Yes, that is the Rule of Three.

<u>Explanation:</u>

A destructor can be defined as a special member function of the class that is used to deallocate the memory assigned to the data members of the class after the created objects of the class go out of scope. If we define a destructor or a copy constructor or an operator "=", we need to include the definition of the other two in the class according to the rule of three.

This is because the compiler copies and copy assign the objects of the class in various situations and if these functions are not present, they are implicitly created and called.

Write a character literal representing the (upper case) letter<br> a.

Vlad1618 [11]

The answer would just be 'A'. A literal is an element that directly represents a value. In this case the element that directly represents the value false is simply the character 'A'. When writing the answer the character should be in single quotes as that defines the value as a single character as opposed to a string or another data type.

Svet_ta [14]

Answer:

The correct option is pane.setOnMouseClicked((e) -> System.out.println(e.getX() + ", " + e.getY()));

Explanation:

As the complete question is not provided, the complete question is attached herewith.

In order to handle the underlined location the way is to get the position using the MouseClicked event which will be activated when the mouse is clicked and then the values of X and Y position will be printed.

pane.setOnMouseClicked((e) -> System.out.println(e.getX() + ", " + e.getY()));

The other options are not correct as the handle used in them is not defined for this purpose.
