Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

• Inheritance allows code reusability and saves time and effort in writing new code.

• The existing class is called the parent or base class, and the new class is called the child or derived class.

• The child class inherits all the properties and methods of the parent class and can also add its ...read more

Different classes in Java are used to define objects and their behavior.

• Classes are the building blocks of Java programs.

• They define the properties and methods of objects.

• Some commonly used classes in Java are String, Integer, ArrayList, etc.

• Classes can be inherited to create new classes with additional features.

• Java provides a rich set of predefined classes, and developers can create their own classes.

Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

• Inheritance allows for code reuse and promotes a hierarchical organization of code.

• The existing class is called the superclass or parent class, and the new class is called the subclass or child class.

Java has four different classes: abstract, final, public and default.

• Abstract class cannot be instantiated and is used as a base class for other classes

• Final class cannot be inherited and is used to prevent further modification

• Public class can be accessed from anywhere in the program

• Default class can only be accessed within the same package

• Example: public class MyClass {}

Creating public and private classes in Java is useful for encapsulation and access control.

• Creating a class as public allows it to be accessed from any other class.

• Creating a class as private restricts its access to only within the same class.

• Public classes are typically used for classes that need to be accessed by other classes or modules.

• Private classes are typically used for helper classes or internal implementation...read more

Defect lifecycle is the process of identifying, reporting, fixing, and verifying defects in software.

• Defect is identified by testers during testing

• Defect is reported to development team

• Development team fixes the defect

• Fixed defect is verified by testers

• If defect is not fixed, it goes back to development team

• If defect is fixed, it is closed

I have used Postman for API testing.

• Postman is a popular tool for API testing and has a user-friendly interface.

• It allows us to send requests, view responses, and test different scenarios.

• We can also create collections of requests and run them in a sequence.

• Postman also has features like environment variables and test scripts.

• Other tools for API testing include SoapUI, JMeter, and Rest-Assured.

HTTP requests are messages sent by a client to a server to request for a resource or perform an action.

• HTTP requests are used in web communication to retrieve data or perform actions on a server.

• They consist of a request method (e.g. GET, POST), a URL, and optional headers and body.

• Examples of HTTP requests include GET requests to retrieve web pages and POST requests to submit form data.

The put function is used to update or replace an existing value in a specified key in an object.
