abstraction in java
Abstraction is nothing but the quality of dealing with ideas rather than
events. It basically deals with hiding the internal details and showing
the essential things to the user.abstraction in java

// example on abstract class in java
import java.util.*;
// abstract class
abstract class Shape
{
// abstract method
abstract void sides();
}
class Triangle extends Shape
{
void sides()
{
System.out.println("Triangle shape has three sides.");
}

public static void main(String[] args)
{
Triangle obj1 = new Triangle();

Pentagon obj2 = new Pentagon();
obj2.sides();
}
}abstraction example in java
In my framework I have achieved abstraction
by using collections or Map, because it’s all interface.
Most of the cases I come across using List.
If we want to access elements frequently by using index,
List is a way to go. ArrayList provides faster access if we know index.
If we want to store elements and want them to maintain an order,
List is a better choice.
i) List webs = driver.getWindowHandles();
=>create a list first to store web URLs in list
ii) findElements evaluates multiple elements
so therefore will assigned to List
iii) To handle dynamic elements store it in the list and identify by index:
List all = driver.findElements(By.tagname(“”));
In my framework I follow POM and had situations
where some pages shared similar actions that were similar
but worked slightly different, so I was able to use abstraction
to define those actions and implement them in each page according
to what was needed for that webpageCopyright © 2021 Codeinu
