- Q1. Difference between absolute and relative Xpath
- Ans.
Absolute Xpath starts from the root element, while relative Xpath starts from any node in the DOM structure.
Absolute Xpath starts with a single forward slash (/) and starts selection from the root node.
Relative Xpath starts with a double forward slash (//) and starts selection from the current node or any node in the DOM structure.

- Q1. What is the output of below code class Animal{ Animal(){ System.out.println("animal is created") } class Dog extends Animal{ Dog(){ System.out.println("Dog is created")} class TestSuper4{ pub...
- Ans.
The output of the code will be 'animal is created' followed by 'Dog is created'.
The code defines a class Animal with a constructor that prints 'animal is created'.
It also defines a class Dog that extends Animal, with a constructor that prints 'Dog is created'.
In the main method, an instance of Dog is created, which will trigger the constructors of both Animal and Dog classes.
- Q2. Output of this : System.out.println(10+20+"Hello"+30+40) - Explain
- Q3. Output of this : String name="Hello"; name=name+"There"; system.out.println(name)
- Ans.
The output will be 'HelloThere'
Concatenation of 'Hello' and 'There' results in 'HelloThere'
The final string is printed using System.out.println()
- Q4. StringBuffer buffer=new StringBuffer("Hello") buffer.append("There"); System.out.println(buffer);
- Ans.
The code creates a StringBuffer object with 'Hello' and appends 'There' to it before printing the final string.
StringBuffer is mutable, so the original 'Hello' string can be modified
The append() method adds the specified string to the end of the buffer
The final output will be 'HelloThere'

- Ans.
Option a is valid, option b is valid, option c is invalid.
Option a is valid because ChromeDriver is a subclass of WebDriver, so it can be assigned to a WebDriver reference.
Option b is valid because ChromeDriver is a subclass of WebDriver, so it can be instantiated using a WebDriver reference.
Option c is invalid because WebDriver is an interface and cannot be instantiated directly. It can only be used as a reference typ
- Q6. Program to sort the input in descending order without using inbuild method/functions
- Ans.
Sort input array of strings in descending order without using inbuilt functions
Iterate through the array and compare each element with the rest to find the largest element
Swap the largest element with the first element, then repeat the process for the remaining elements
Continue this process until the array is sorted in descending order
- Q7. Difference between findElement and findElements
- Ans.
findElement returns the first matching element on the page, while findElements returns a list of all matching elements.
findElement returns a single WebElement matching the locator provided
findElements returns a list of WebElements matching the locator provided
findElement will throw NoSuchElementException if no element is found, while findElements will return an empty list
- Q8. Difference between getwindowhandle and getwindowhandles() and what is output type
- Ans.
getwindowhandle returns the handle of the current window, getwindowhandles() returns handles of all open windows
getwindowhandle returns a single window handle, while getwindowhandles() returns a set of window handles
getwindowhandle is used to switch between windows in Selenium WebDriver
Output type of getwindowhandle is String, while output type of getwindowhandles() is Set
- Q9. Question on finding the xpaths on website
- Q10. Difference between String and StringBuilder?
- Ans.
String is immutable, while StringBuilder is mutable and more efficient for concatenating strings.
String is immutable, meaning its value cannot be changed once it is created.
StringBuilder is mutable, allowing for modifications to the string without creating a new object.
StringBuilder is more efficient for concatenating multiple strings as it does not create new objects each time.
Example: String str = "Hello"; StringBuil

Example of compile-time polymorphism: function overloading in Java.
Example of runtime polymorphism: method overriding in Java
