The code demonstrates exception handling, resulting in an output of 2 due to incrementing variable I in catch and finally blocks.
The code throws a NullPointerException which is caught in the catch block.
In the catch block, I is incremented from 0 to 1.
The finally block executes regardless of exception, incrementing I from 1 to 2.
The final output printed is the value of I, which is 2.
Identify and print duplicate names from a string array that start with 'B'.
1. Create a string array with names, e.g., ['Bob', 'Alice', 'Bill', 'Bob', 'Bobby'].
2. Use a HashMap or dictionary to count occurrences of each name.
3. Iterate through the array and check for names starting with 'B'.
4. Print names that have a count greater than 1, e.g., 'Bob' and 'Bill' if they are duplicates.
TestNG annotations are used to define test methods, configuration, and grouping in automated testing.
@Test: Marks a method as a test method. Example: @Test public void testMethod() {}

In a runner class, tags help organize and filter test cases for execution in automation testing frameworks.
Tags are used to categorize tests, e.g., @smoke, @regression.
They allow selective execution, e.g., running only @smoke tests.
Tags can be combined, e.g., @regression and @critical.
In Cucumber, tags are specified in the feature file, e.g., @login.
In TestNG, tags can be implemented using groups in XML configuration.
Regression testing checks existing features after changes, while smoke testing verifies basic functionality post-deployment.
Regression testing ensures that new code changes do not adversely affect existing functionalities.
Smoke testing is a preliminary test to check if the basic functions of an application work.
Example of regression testing: After a new feature is added, testing all existing features to ensure they sti...
