Encapsulation is the process of hiding implementation details and exposing only necessary information.

• Encapsulation is a fundamental concept in object-oriented programming.

• It helps in achieving data abstraction and information hiding.

• It allows for better control over the data and prevents unauthorized access.

• Example: A class in Java can have private variables and public methods to access them.

• Example: A capsule is a good analogy for encapsulation as it hides the medicine insi...read more

Java is a high-level programming language, while C++ is a general-purpose programming language.

• Java is platform-independent, while C++ is platform-dependent.

• Java uses automatic memory management (garbage collection), while C++ requires manual memory management.

• Java has a simpler syntax and is easier to learn, while C++ has a more complex syntax.

• Java is mainly used for developing web and enterprise applications, while C++ is commonly used for system-level programming and game ...read more

Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.

• Polymorphism is a fundamental concept in object-oriented programming.

• It allows a single interface to be used for different types of objects.

• Polymorphism is achieved through method overriding and method overloading.

• Example: A shape class with different subclasses like circle, square, and triangle.

• All these subclasses can be treated as shapes and...read more

Manual testing allows for human intuition and creativity but can be time-consuming and prone to human error.

• Advantages of manual testing include human intuition and creativity in identifying issues, flexibility to adapt test cases on the fly, and cost-effectiveness for small projects.

• Disadvantages of manual testing include time-consuming nature, potential for human error, difficulty in reproducing test cases, and lack of scalability for large projects.

• Example: Manual testing ...read more

A tuple is an immutable sequence of elements in Python.

• Tuples are defined using parentheses ()

• Tuples can contain elements of different data types

• Elements in a tuple can be accessed using indexing

• Tuples are immutable, meaning their elements cannot be modified once created

Manual software testing is the process of manually testing software for defects without the use of automation tools.

• Manual testing involves testers executing test cases by hand to identify bugs and issues.

• It is time-consuming and requires human intervention for each test step.

• Manual testing is often used for exploratory testing, usability testing, and ad-hoc testing.

• Examples of manual testing include regression testing, smoke testing, and user acceptance testing.

Different tests in software testing include unit testing, integration testing, system testing, and acceptance testing.

• Unit testing focuses on testing individual components or modules of the software.

• Integration testing checks if different modules work together correctly.

• System testing validates the entire system against the requirements.

• Acceptance testing ensures that the software meets the user's expectations.

• Other types of tests include regression testing, performance testi...read more

Software is a set of instructions that tell a computer how to perform specific tasks or functions.

• Software is a collection of programs, data, and instructions that enable a computer to perform tasks.

• It can be categorized into system software (e.g. operating systems) and application software (e.g. word processors).

• Examples of software include Microsoft Windows, Adobe Photoshop, and Google Chrome.
