Relationships in Classes

What is a relationship between classes in object-oriented programming?

• Inheritance between classes

• Encapsulation between classes

• Polymorphism between classes

• Connection or association between classes

What is the purpose of a relationship between classes?

• To determine the visibility of class members

• To define the attributes of a class

• To establish a connection or association between classes

• To create a hierarchy between classes

What are the different types of relationships between classes?

• inheritance, association, aggregation, and composition

• polymorphism

• dependency

• encapsulation

What is an association relationship between classes?

• A dependency relationship that represents one class depending on another class.

• A hierarchical relationship that represents a parent-child relationship between classes.

• A behavioral relationship that represents the interaction between two or more classes.

• A structural relationship that represents a connection or link between two or more classes.

What is an aggregation relationship between classes?

• An aggregation relationship between classes represents a dependency relationship where one class relies on another class for its functionality.

• An aggregation relationship between classes represents a many-to-many relationship where one class can be associated with multiple instances of another class.

• An aggregation relationship between classes represents a parent-child relationship where one class is the parent and the other class is the child.

• An aggregation relationship between classes represents a whole-part relationship where one class is composed of one or more instances of another class.

What is a composition relationship between classes?

• A composition relationship between classes is a weak type of association where one class is composed of one or more instances of another class.

• A composition relationship between classes is a type of inheritance where one class inherits properties and methods from another class.

• A composition relationship between classes is a type of polymorphism where one class can have multiple forms or behaviors.

• A composition relationship between classes is a strong type of association where one class is composed of one or more instances of another class.

What is an inheritance relationship between classes?

• An inheritance relationship between classes is a relationship where one class shares the properties and methods of another class.

• An inheritance relationship between classes is a relationship where one class inherits the properties and methods of another class.

• An inheritance relationship between classes is a relationship where one class copies the properties and methods of another class.

• An inheritance relationship between classes is a relationship where one class extends the properties and methods of another class.

What is a dependency relationship between classes?

• A dependency relationship between classes is a relationship where one class inherits from another class.

• A dependency relationship between classes is a relationship where two classes are completely independent of each other.

• A dependency relationship between classes is a relationship where one class depends on another class for its functionality or behavior.

• A dependency relationship between classes is a relationship where two classes have a bidirectional association.

What is a multiplicity in a relationship between classes?

• Multiplicity in a relationship between classes refers to the number of instances of one class that can be associated with a single instance of another class.

• Multiplicity in a relationship between classes refers to the number of attributes in each class.

• Multiplicity in a relationship between classes refers to the number of methods in each class.

• Multiplicity in a relationship between classes refers to the number of subclasses in each class.

How can you represent relationships between classes using UML diagrams?

• By using connectors such as association, aggregation, composition, and generalization.

• By using connectors such as association, aggregation, composition, and realization.

• By using connectors such as association, aggregation, composition, and implementation.

• By using connectors such as association, aggregation, composition, inheritance, and dependency.
