COS 9 – JAVA PROGRAMMING MIDTERM 1st Week Exception and Assertion Exceptions – are a mechanism used by many programming languages to describe what to do when something unexpected happens. Common Exceptions: NullPointerException – this is attempt to access an attribute or method of an does not refer to an object. FileNotFoundException – this is attempt to read from a file that does not exit. NumberFormatException – this is attempt to parse a string into a number. ArithmeticException

STATEMENT OF PURPOSE(SOP) I have developed a keen interest to further develop my skills in the arena of Programming in Computer Science. Challenging task in developing an application has always thrilled me during my graduation in Computer Science‚ which lead me to pursue a post graduate degree. There is a saying‚ which says‚ “The only thing permanent in life is change”. This perfectly holds true to the world of Computer Science where novel ideas are not a novelty. It is this novelty that entices

Run Time Polymorphism Compile time polymorphism is used for Function overloading Runtime is used for implementing virtual functions overriding etc. C# 5)What is an indexer? Indexers are used for treating an object as an array. The indexers are usually known as smart arrays in C# community. Defining a C# indexer Is much like defining

keyboard. 2. I found six other ways of diagramming entities and relations. The six other methods of diagramming entities and relations are as follows: a. Peter Chen’s diagram b. Information Engineering c. Richard Barker’s notation d. Object Role Modeling (ORM) e. The Unified Modeling Language (UML) f. Extensible Markup Language (XML) The similarities that I found are that Peter Chen’s‚ Information Engineering‚ and UML diagrams all use square cornered shapes for entities. Also

Procedures tend to perform actions as with functions these are reusable Classes Part of the object-oriented programming paradigm a class contains both data and functions that describe a real world thing Objects A concrete instance of a class complete with its personal data Abstraction of data One of the key principle ideas behind the creation of classes in data abstraction the data type is less important

SYSTEMS ANALYSIS AND DESIGN PROTOTYPING We know from the world of engineering that a manufacturer will develop a prototype model before mass producing the final product. So why not apply this concept to the development of a software product? This is what the pioneers of prototyping have set out to achieve by attempting to demonstrate how a system or a component of a computer-based information system will function in its environment. Users find such demonstrations very helpful in visualising
