What is the difference between Overloading and Overriding?
When you have two methods of the same name but having different properties, the case is called Overloading. On the other hand, Overriding refers to a situation where two methods with the same name and properties occur, but the two occurring in a parent and child class respectively.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

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.what is method overloading

In my framework==
I use implicit wait in Selenium. Implicit wait
is an example of overloading. In Implicit wait
we use different time stamps such as SECONDS, MINUTES, HOURS etc.,
A class having multiple methods with
same name but different parameters
is called Method Overloadingmethod overloading

// 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));
