BGP (Border Gateway Protocol) is a routing protocol used to exchange routing information between different autonomous systems (AS).

• BGP is used to exchange routing information and prefixes between different AS numbers.

• BGP helps in determining the best path for data to travel between networks.

• BGP operates on TCP port 179.

• BGP uses attributes like AS path, next hop, and local preference to make routing decisions.

• Example: B...read more

Product management involves overseeing the development, marketing, and production of a product from start to finish.

• Involves identifying market needs and opportunities

• Includes developing product strategies and roadmaps

• Requires coordinating cross-functional teams such as engineering, marketing, and sales

• Involves managing the product lifecycle from concept to end-of-life

• Includes analyzing market trends and competition

Bending moment is a measure of the bending effect on a beam or structural element.

• Bending moment is the algebraic sum of moments about the neutral axis of a section of a beam or structural element.

• It is caused by external forces acting on the beam, resulting in a bending or flexural deformation.

• Bending moment is calculated using the formula: M = F * d, where M is the bending moment, F is the force applied, and d is the...read more

Strain is the deformation of a material under load, while stress is the force applied to a material per unit area.

• Strain is a measure of how much a material deforms under stress.

• Stress is the force applied to a material per unit area.

• Strain is a dimensionless quantity, while stress is measured in units of force per unit area (such as N/m^2 or Pa).

• Strain can be either tensile (stretching) or compressive (squeezing), whi...read more

Heat treatment is a process used to alter the physical and sometimes chemical properties of a material through heating and cooling.

• Heat treatment involves heating a material to a specific temperature, holding it at that temperature for a certain amount of time, and then cooling it at a controlled rate.

• The purpose of heat treatment is to improve the material's hardness, strength, toughness, ductility, and other properti...read more

Structures are rigid bodies that support loads, while links are flexible elements that connect structures.

• Structures are typically made of rigid materials like steel or concrete

• Links are often made of flexible materials like cables or chains

• Structures provide support and stability to a system

• Links allow for movement or flexibility within a system

• Example: A bridge is a structure that supports loads, while the cables con

Find min and max from List of Integers using Java 8 streams.

• Use the `stream()` method on the List to create a stream of integers.

• Use the `min()` method to find the minimum value.

• Use the `max()` method to find the maximum value.

Find 2nd largest element using Java 8 streams from a list of integers.

• Sort the list of integers in descending order using streams.

• Skip the first element to get the second largest element.

Increase the values of a list of integers by 2 and create a new list.

• Iterate through the list of integers

• For each integer, add 2 to its value

• Create a new list with the updated values

Java has introduced several new features in recent versions.

• Java 8 introduced lambda expressions, which allow for functional programming.

• Java 8 also introduced the Stream API for processing collections of data.

• Java 9 introduced the module system, which provides better encapsulation and modularity.

• Java 10 introduced local variable type inference, allowing the omission of explicit type declarations.

• Java 11 introduced the...read more

The @Component and @Repository annotations are used in Spring Framework for different purposes.

• Both annotations are used to define beans in the Spring container.

• @Component is a generic stereotype annotation for any Spring-managed component.

• @Repository is a specialization of @Component used for DAO classes.

• The @Repository annotation provides additional exception translation for data access exceptions.

• Using @Repository i...read more

The @Entity annotation is used in Java to mark a class as an entity, which represents a table in a relational database.

• The @Entity annotation is part of the Java Persistence API (JPA) and is used in object-relational mapping (ORM) to map Java objects to database tables.

• It is typically used in conjunction with other JPA annotations like @Table, @Column, and @Id.

• The @Entity annotation is used to define the entity name, s...read more

The database is configured by setting up the necessary parameters and configurations to ensure proper functioning and performance.

• Database configuration involves defining the database schema, tables, and relationships.

• It includes setting up indexes and constraints for data integrity.

• Configuring database security measures like user access control and permissions.

• Tuning database performance by optimizing query execution ...read more

Dockerfile is a text file that contains instructions to build a Docker image.

• Dockerfile is used to automate the creation of Docker images.

• It specifies the base image, dependencies, environment variables, and commands to run.

• Each instruction in the Dockerfile creates a new layer in the image.

• Dockerfile can be version controlled and shared to ensure consistent builds.

• Example: FROM ubuntu:latest RUN apt-get update && apt-...read more

CI/CD is a software development practice that enables frequent and automated code integration, testing, and deployment.

• CI/CD stands for Continuous Integration and Continuous Deployment.

• It involves automating the process of integrating code changes, running tests, and deploying the application.

• CI/CD helps in reducing manual errors, improving code quality, and increasing development speed.

• Tools like Jenkins, GitLab CI/CD...read more

Mutable classes in Java are classes whose state can be modified after creation.

• Mutable classes allow changing their internal state

• They can have mutable fields or methods that modify their state

• To create a mutable class, define fields with non-final modifiers

• Provide public methods to modify the state of the class

Inheritance in Java allows a class to inherit properties and behaviors from another class.

• Inheritance is achieved using the 'extends' keyword in Java.

• Subclasses can access the methods and fields of their superclass.

• Java does not support multiple inheritance, but a class can implement multiple interfaces.

Use SQL query with ORDER BY and LIMIT to find the last element in a table.

• Use ORDER BY column_name DESC to sort the data in descending order.

• Use LIMIT 1 to retrieve only the last element.

HTML5 is the latest version of HTML with new features and improvements.

• HTML5 supports new elements like

  ,

• HTML5 introduces new APIs like Geolocation, Drag and Drop, Local Storage, Canvas, WebSockets, etc.

• HTML5 supports multimedia elements like

• HTML5 has improved semantics and accessibility features compared to HTML.
