BRD and FRD are both documents used in the software development process, but they serve different purposes.
BRD stands for Business Requirements Document and focuses on the business needs and objectives of a project.
FRD stands for Functional Requirements Document and outlines the specific functionalities and features of a software system.
BRD is more high-level and describes the 'what' and 'why' of a project, while FRD i...

Bias is error due to overly simplistic assumptions, variance is error due to overly complex models.
Bias is the error introduced by approximating a real-world problem, leading to underfitting.
Variance is the error introduced by modeling the noise in the training data, leading to overfitting.
High bias can cause a model to miss relevant relationships between features and target variable.
High variance can cause a model to ...
Parametric models make strong assumptions about the form of the underlying data distribution, while non-parametric models do not.
Parametric models have a fixed number of parameters, while non-parametric models have a flexible number of parameters.
Parametric models are simpler and easier to interpret, while non-parametric models are more flexible and can capture complex patterns in data.
Examples of parametric models inc...

OOPs concepts in Java include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a subclass to inherit properties and methods from a superclass.
Polymorphism allows objects to take on multiple forms and behave differently based on their context.
Encapsulation hides the implementation details of an object and only exposes necessary information.
Abstraction allows for the creation of abstract class...
Interfaces define contracts for behavior, while inheritance allows for code reuse and polymorphism.
Interfaces allow for loose coupling and abstraction, enabling multiple implementations of the same behavior.
Inheritance allows for code reuse and extension of existing classes, reducing code duplication.
Polymorphism allows objects of different classes to be treated as if they were of the same class, simplifying code and i
SQL query for joining tables
Use JOIN keyword to combine two or more tables based on a related column
Specify the columns to be selected using SELECT keyword
Use ON keyword to specify the condition for joining the tables
Different types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN
Used Java concepts such as inheritance, polymorphism, and exception handling in my project.
Implemented inheritance to create a base class and derived classes with specific functionalities.
Utilized polymorphism to allow objects of different classes to be treated as if they were of the same class.
Implemented exception handling to handle errors and prevent program crashes.
Used interfaces to define a set of methods that a ...
Overloading is having multiple methods with the same name but different parameters. Overriding is having a method in a subclass with the same name and parameters as a method in the superclass.
Overloading is used to provide different ways to call a method with different parameters
Overriding is used to provide a specific implementation of a method in a subclass
Overloading is resolved at compile-time while overriding is r...
