Software reuse is the practice of utilizing existing software components to accelerate development, enhance quality, and lower costs. It encompasses various types such as code reuse, design reuse, and component reuse, and employs techniques like libraries, frameworks, and design patterns. The benefits include reduced development time, increased productivity, and improved consistency across applications.

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. ParaTechniques for Software Reusemeterized
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.
