Answers for "method overriding"

what's method overriding

Overriding means same method name and same parameter, 
occur in different class that has inheritance relationship. 
we use method overriding to implement specific functionality to the method.

Example: get method
WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome

WebDriver driver = new FireFoxDriver();
driver.get("URL") ==> opens the url from Firefox

we can only override instance methods and method override 
takes place in sub class.
instance method that we are going to override cannot be private and final

method overriding java

Method Overloading: 
Access modifier can be same or different, 
Return-Type can be same or different, 
Parameters MUST be different, Method name MUST be same, 
any method can be overloaded

Method Overriding:
After a method is inherited it is possible to change 
the implantation of the method in the child class. 
This concept is called overriding. 
Method name, Parameter, and Return-Type MUST be same
access modifier MUST be same or more visible, 
MUST happen in the sub class, 
ONLY the instance methods can be overridden
@Override annotation MUST be applicable. 
Static and Constructor cannot be override.
We can use the @Override annotation before the method 
to declare the overriding.
EXAMPLE: get method WebDriver driver = new ChromeDriver(); 
driver.get("URL") ==> opens the url from chrome

method overloading

//https://www.geeksforgeeks.org/overloading-in-java/
// Java program to demonstrate working of method
// overloading in Java. 
  
public class Sum { 
  
    // Overloaded sum(). This sum takes two int parameters 
    public int sum(int x, int y) 
    { 
        return (x + y); 
    } 
  
    // Overloaded sum(). This sum takes three int parameters 
    public int sum(int x, int y, int z) 
    { 
        return (x + y + z); 
    } 
  
    // Overloaded sum(). This sum takes two double parameters 
    public double sum(double x, double y) 
    { 
        return (x + y); 
    } 
  
    // Driver code 
    public static void main(String args[]) 
    { 
        Sum s = new Sum(); 
        System.out.println(s.sum(10, 20)); 
        System.out.println(s.sum(10, 20, 30)); 
        System.out.println(s.sum(10.5, 20.5)); 
    } 
}

method overriding

Overriding means same method name and same parameter, 
occur in different class that has 
inheritance relationship. 
we use method overriding to implement 
specific functionality to the method. 

Examples are get and navigate methods
of different drivers in Selenium .

Example: get method
WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome

WebDriver driver = new FireFoxDriver();
driver.get("URL") ==> opens the url from Firefox

we can only override instance methods and method override 
takes place in sub class.
instance method that we are going to override cannot be private and final
Example: get method
WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome

WebDriver driver = new FireFoxDriver();
driver.get("URL") ==> opens the url from Firefox

we can only override instance methods and method override 
takes place in sub class.
instance method that we are going to
override cannot be private and final

method override

using method-override in your index.js
1. npm install method-override --save
2. var methodOverride = require("method-override");
3. app.use(methodOverride("_method"));
//'_method' is what methodOverride will look for
method override in your UPDATE route: 
* <form action = "/campgrounds/<%=campground._id%>/edit?_method=PUT" 
	method = "POST">
and EDIT routes:
