Exception handling in Java is a mechanism to handle runtime errors and prevent program crashes.

• Exceptions are objects that are thrown at runtime when an error occurs.

• Try block is used to enclose the code that might throw an exception.

• Catch block is used to handle the exception and provide a specific response.

• Finally block is used to execute code regardless of whether an exception is thrown or not.

• Example: try { // code that might throw exception } catch (Exception e) { // han...read more

OOPS (Object-Oriented Programming) is a programming paradigm that uses objects to represent real-life entities.

• Encapsulation: Combining data and methods into a single unit (class) to hide implementation details.

• Inheritance: Creating new classes (subclasses) from existing classes (superclasses) to reuse code and extend functionality.

• Polymorphism: Using a single interface to represent different forms (classes) of objects.

• Abstraction: Simplifying complex systems by breaking them...read more

Signature violation error occurs when a digital signature is invalid or corrupted.

• It happens when a digital signature is not properly verified.

• It can occur due to tampering with the signed data.

• It can also happen if the certificate used to sign the data is expired or revoked.

• Examples include SSL certificate errors and code signing errors.

OOP (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.

• OOP in Java involves creating classes and objects, encapsulation, inheritance, and polymorphism.

• Classes are blueprints for objects, defining their properties and behaviors.

• Encapsulation involves bundling data (attributes) and methods (functions) that operate on the data within a single unit.

• Inheritance allows a class to inherit properties and methods fr...read more

Developed a Java project for a banking application

• Used Java to create backend logic for customer transactions

• Implemented security features to protect sensitive data

• Integrated with external APIs for currency exchange rates

A class is a blueprint for creating objects, while an object is an instance of a class.

• A class defines the properties and behaviors of objects.

• An object is a specific instance of a class.

• Classes can be used to create multiple objects with similar characteristics.

• Objects can interact with each other by calling methods defined in their class.

• Example: Class 'Car' defines properties like 'color' and behaviors like 'drive'. An object 'myCar' can be created from this class.

The order of execution in Salesforce refers to the sequence in which various operations are performed during the processing of a record.

• The order of execution includes triggers, validation rules, workflow rules, processes, assignment rules, and more.

• Triggers are executed before validation rules, and workflow rules are executed after triggers.

• The order of execution can be controlled using the 'Order of Execution' settings in Salesforce setup.

• Understanding the order of executio...read more

Creating a task involves defining requirements, designing a solution, coding, testing, and deploying.

• Define requirements for the task

• Design a solution based on requirements

• Code the task using appropriate programming languages

• Test the task to ensure it functions correctly

• Deploy the task for use by end users

SQL is a programming language used for managing and manipulating relational databases.

• SQL stands for Structured Query Language

• It is used to create, modify, and retrieve data from databases

• SQL is a declarative language, meaning you specify what you want to achieve rather than how to achieve it

• Common SQL commands include SELECT, INSERT, UPDATE, and DELETE

• SQL is used in various database management systems like MySQL, Oracle, and SQL Server

Oops concept in C++ refers to Object-Oriented Programming principles like inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance allows a class to inherit properties and behavior from another class.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• Encapsulation hides the internal state of an object and only exposes necessary functionality.

• Abstraction focuses on the essential characteristics of an object while ignor...read more
