Object-Oriented Programming Paradigm Advantages * Because of the concept of inheritance in OO programming‚ existing codes can be easily modified because new codes can be added with little modifications made. That is to say it is easily extensible and codes can be easily re-used. * OOP provides a clear program structure because the solution to be developed can be broken down into objects and approached as such. This gives room for maintainability of the program because problems would be easy

Answer: The UML architecture is based on the meta object facility‚ which defines the foundation for creating modelling language. They are precise enough to generate the entire application. A fully executable UML can be deployed to multiple platforms using different technologies and can be used with all processes throughout the software development cycle. UML is designed to enable users to develop an expressive‚ ready to use visual

Modifiers – certain reserved words that specify the properties of the data‚ methods‚ and classes and how they can be used. Statements – a statement represents an action or a sequence of actions. Every statement in Java ends with a semicolon (;) ++i Blocks – are used to group the components of the program‚ for example
