KRA (Key Result Area) and KPI (Key Performance Indicator) are metrics used to evaluate performance and success in various roles.
KRA defines the specific areas where an employee is expected to achieve results, e.g., sales targets.
KPI measures the performance against the KRA, e.g., percentage of sales target achieved.
KRA is broader and focuses on outcomes, while KPI is specific and quantifiable.
Example of KRA: Custo...
Urgency refers to the speed of response needed, while priority indicates the importance of the issue in ITIL processes.
Urgency is about how quickly a resolution is needed; for example, a system outage may be urgent.
Priority is determined by the impact on the business; for instance, a critical application failure has high priority.
An urgent issue might not always be high priority; e.g., a minor bug affecting a non-...

Element Not Found: Happens when the automation script cannot locate a UI element, e.g., a missing input field on a form.
Stale Element Reference: Occurs when a web element is no longer attached to the ...
Method overloading allows multiple methods with the same name but different parameters; overriding replaces a method in a subclass.
Method Overloading: Same method name, different parameter types or counts. Example: 'add(int a, int b)' and 'add(double a, double b)'.
Method Overriding: Redefining a method in a subclass that already exists in the parent class. Example: 'void display()' in both parent and child.

The event loop is a programming construct that manages asynchronous operations in JavaScript, enabling non-blocking execution.
Single Threaded: JavaScript runs on a single thread, meaning it can only execute one operation at a time, which is managed by the event loop.
Call Stack: The event loop works with the call stack, where functions are executed in a last-in, first-out manner.
Web APIs: Asynchronous operations li...
Event-driven programming in JavaScript enables responsive and interactive applications by reacting to user actions and events.
Asynchronous Handling: JavaScript uses event-driven programming to handle asynchronous events, allowing the application to remain responsive while waiting for tasks like API calls.
User Interaction: Events such as clicks, key presses, and mouse movements can trigger functions, enabling dynam...
The server-side model processes requests on the server, generating dynamic content and managing data before sending it to the client.
Request Handling: The server receives requests from clients, processes them, and sends back responses, often using frameworks like Express.js.
Dynamic Content Generation: Server-side applications can generate HTML dynamically based on user input or database queries, e.g., rendering a ...
Spring Batch supports multi-threading to improve performance and efficiency in batch processing through parallel execution of tasks.
Task Executors: Use Spring's TaskExecutor to manage threads for parallel processing, allowing multiple steps to run concurrently.

(5 Questions)
- Q1. What is the architecture of the Java Virtual Machine (JVM)?
- Ans.
The Java Virtual Machine (JVM) is an abstract computing machine that enables a computer to run Java programs.
JVM is platform-independent and converts Java bytecode into machine code.
It consists of class loader, runtime data areas, execution engine, and native method interface.
JVM memory is divided into method area, heap, stack, and PC register.
Examples of JVM implementations include Oracle HotSpot, OpenJ9, and GraalVM.
- Q2. What is the default connection pooling in Spring Boot, and how can it be customized?
- Ans.
The default connection pooling in Spring Boot is HikariCP, which can be customized through properties in the application.properties file.
HikariCP is the default connection pooling library in Spring Boot, known for its high performance and low overhead.
To customize the connection pooling, you can modify properties like 'spring.datasource.hikari.*' in the application.properties file.
For example, you can set maximum pool ...
- Q3. What are the best practices for optimizing a Spring Boot application?

- Q4. What is a heap dump, and how can it be used to identify memory leaks?
- Ans.
A heap dump is a snapshot of the memory usage of a Java application at a specific point in time.
Heap dumps can be generated using tools like jmap or VisualVM.
They provide detailed information about objects in memory, their sizes, and references.
Analyzing a heap dump can help identify memory leaks by pinpointing objects that are consuming excessive memory.
Common signs of memory leaks in a heap dump include a large numbe...
- Q5. How can you diagonally iterate through and print the elements of a 2D array?program
- Ans.
Diagonally iterate through and print elements of a 2D array of strings.
Use nested loops to iterate through rows and columns of the 2D array.
Calculate the diagonal elements by incrementing row and column indices together.
Print the elements as you iterate through the diagonal of the array.

- Q1. How to check if a file exist or not in the Linux shell scripting? Ans: using -e $filename
- Ans.
In Linux shell scripting, use the -e flag to check if a file exists.
Use the command: if [ -e $filename ]; then echo 'File exists'; fi
The -e flag checks for the existence of a file or directory.
You can also use -f for regular files: if [ -f $filename ]; then echo 'Regular file exists'; fi
For directories, use -d: if [ -d $dirname ]; then echo 'Directory exists'; fi
- Q2. One python coding question in which we have to remove n number of characters from string. Persis**** As there are 4 stars we have to remove 4 characters "sisr" and return the result.
- Ans.
This task involves removing a specified number of characters from a string based on asterisks indicating the count.
Identify the number of asterisks in the string to determine how many characters to remove.
Use string slicing to remove the specified characters from the original string.
Example: For 'Persis****', remove 4 characters to get 'Pe'.
Consider edge cases, such as when the number of asterisks exceeds the length of...
