overloading e overriding java code example
Example 1: what is method overloading and method overriding in Java?
Method overloading is providing two separate methods in a class with the same name but different arguments, while the method return type may or may not be different, which allows us to reuse the same method name.
Method overriding means defining a method in a child class that is already defined in the parent class with the same method signature, same name, arguments, and return type
Example 2: overriding in java
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
