11. Compare and contrast abstract classes and interfaces. Why would you use an abstract class? Why would u use an interface? -abstract class‚ ex: (public abstract class Employee{...}) -For related classes only‚ inheritance (last week examples) -extends keyword -contains both instance and static variables -contains both abstract and concrete methods only An abstract class is only to be sub-classed (inherited from). In other words‚ it only allows other classes to inherit from it but cannot

August 2014. DATAFLOW PROGRAMMING: The programming language used in Lab VIEW‚ also referred to as G‚ is a dataflow programming language. Execution is determined by the structure of a graphical block diagram (the Lab VIEW-source code) on which the programmer connects different function-nodes by drawing wires. These wires propagate variables and any node can execute as soon as all its input data become available. Since this might be the case for multiple nodes simultaneously‚ G is inherently capable

Use one leading underscore for non-public methods and instance variables. A programmer should use two leading underscores to avoid name clashes with subclasses. Lower case words with underscores should be used for naming functions. Capitalized words with underscores

Pseudocode is sometimes used as a detailed step in the process of developing a program. It allows designers or lead programmers to express the design in great detail and provides programmers a detailed template for the next step of writing code in a specific programming language. Because pseudocode is detailed yet readable‚ it can be inspected by the team of designers and programmers as a way to ensure that actual programming is likely to match design specifications. Catching errors at the pseudocode

Stearns’ work was carried out in the greater Boston area by four programmers namely: Tom Andrews‚ Cy Crane‚ Marge Dector and Megan Harris in a virtual environment. The virtual work team was asked to make a major program change to help do work more efficiently so they developed programming tools called macros. Cy Crane

analyses how this type of expert system works and deduces it down to the conclusion that for an intelligent programme to function‚ there has to be a programmer in the background pulling all the strings in the background writing all the coding required for the system to work. Which is true to say the least‚ but as technology advances the need for the programmer might eventually be eliminated leaving a system that is so intelligent it has the ability to learn from its own mistakes. Some might argue that
