3. What is Software Reuse? Definition: Software reuse is the process of using existing software components in new applications to reduce development time, improve quality, and reduce costs. Explanation: Can involve code, designs, documentation, or entire systems.

4. Benefits of Software Reuse Reduced Development Time : Less time spent reinventing the wheel. Improved Quality : Reused components have been tested and debugged. Cost Savings : Reduces the cost of new projects. Increased Productivity : Allows developers to focus on higher-level problems. Consistency : Promotes uniformity across different applications.

5. Default Constructor: If a class does not explicitly define any constructors, Java provides a default constructor. This constructor initializes the object with default values (e.g., numeric variables to 0, object references to null).

6. Types of Software Reuse Code Reuse: Reusing source code components.Design Reuse: Reapplying design patterns or architectural designs.Object -Oriented Reuse: Inheritance and polymorphism allow for code reuse in object-oriented programming.Component Reuse: Use of pre-built software components like libraries or frameworks.Service Reuse: Reusing services in SOA (Service-Oriented Architecture).

7. Para Techniques for Software Reuse meterized Constructors: Libraries & APIs : Use pre-built libraries and APIs to streamline coding efforts. Frameworks : Employ frameworks like .NET or React for structural reuse. Design Patterns : Apply proven design patterns to solve common development issues. Code Repositories : Utilize platforms like GitHub for finding reusable code. Software Product Lines : Develop software families based on common features.
