What are the mechanisms to implement object-oriented model?

Encapsulation, inheritance, and polymorphism are usually given as the three fundamental principles of object-oriented languages (OOLs) and object-oriented methodology.

Methods of Object class

Object-Oriented Terminology object: an object is an element (or instance) of a class; objects have the behaviors of their class. The object is the actual component of programs, while the class specifies how instances are created and how they behave.

Object-oriented design is built upon a sound engineering foundation, whose elements we collectively call the object model. The object model encompasses the principles of abstraction, encapsulation, modularity, hierarchy, typing, concurrency, and persistence.

An object model helps describe or define a software/system in terms of objects and classes. It defines the interfaces or interactions between different models, inheritance, encapsulation and other object-oriented interfaces and features.

What are the different methods in Object class?

• int hashCode(): Returns hashcode generated for the object.
• boolean equals(Object obj): Returns true if the current object and parameter object are equal.
• Object clone(): Returns the copy of current object.
• String toString(): Convert the object into a string representation.

A class can implement more than one interface. Body: The class body surrounded by braces, { }. Constructors are used for initializing new objects. Fields are variables that provides the state of the class and its objects, and methods are used to implement the behavior of the class and its objects.

When an object of a class is created, the class is said to be instantiated. All the instances share the attributes and the behavior of the class. But the values of those attributes, i.e. the state are unique for each object.

1) We created a custom Main class with the class keyword. 2) We created the fullThrottle () and speed () methods in the Main class. 3) The fullThrottle () method and the speed () method will print out some text, when they are called. 4) The speed () method accepts an int parameter called maxSpeed – we will use this in 8).

1) What is the difference between both the way of creating class objects. When you instantiate object with automatic storage duration, like this (where X is some class): You are creating an object which will be automatically destroyed when it goes out of scope. On the other hand, when you do:
