object oriented programing code example

Example 1: object oriented programming languages

Object oriented programming languages include:

Java
JavaScript
Python
C++
Visual Basic .NET
Ruby
Scala
PHP

These are just the main ones, there's much more out there.

Example 2: object-oriented programming

class Person {
 void walk() {
  System.out.println(“Can Run….”);
 }
}
class Employee extends Person {
 void walk() {
  System.out.println(“Running Fast…”);
 }
 public static void main(String arg[]) {
  Person p = new Employee(); //upcasting
  p.walk();
 }
}

Example 3: object oriented programming

//	OOP is a programming paradigm found in many languages today.
//	Generally, an object is an instance of a Class.
//	Here's a Java example:
public class Car
{
	private double speed;
  	
  	public Car(double initialSpeed)	//	Constructor, most common way to initialize objects of a class.
    {
    	speed = initialSpeed;
    }
  
  	//	Accessor methods, aka getters
  	public double getSpeed()
    {
		return speed;
     	//	This is an example of encapsulation, where
      	//	methods are used to hide the implementation details
		//	and ensure the programmer can't modify things they shouldn't be able to.
    }
  
  	public void accelerate()
    {
		speed++;
    }
  
  	public void slowDown()
    {
    	speed--;
    }
}
