The focus of such languages is on structure. java: IT is the launcher for Java applications. Javadoc: It is the API documentation generator: applet viewer: It can be used to run and debug applets without a web browser. By definition, Generics are a set of Java language features that allow the programmer to use Generic types and functions and thus ensure type safety. We make the following observations about structured programming: • Structured programming is narrowly oriented towards solving one particular problem • It would be nice if our programming efforts could be oriented more broadly • Structured programming is carried out by gradual decomposition of the functionality reusability. Reusability-- The stable interfaces provided by frameworks enhance reusability by defining generic components that can be reapplied to create new applications. Benefits of reusability in code is 1 already developed program used in another program .To avoid ambiguity in code Car is a vehicle and bike is also vehicle and when you got the relation is (is-a) then always prefer for inheritance. Furthermore, Nair and Selvarani (2010) examine the reusability of a certain class based on the values of DIT, RFC and WMC, as defined in the Chidamber et al. ... enables reusability of an instant of an already implemented class within a new class while hiding & protecting the method and properties from the client classes. Object oriented programming generally support 4 types of relationships that … It is said that a graph is characterized by its degree distribution. This reusability is possible due to the relationship b/w the classes. This blog post I've found from 2009 has a nice way of looking at the problem of comparing the ease of use with the ability to reuse. This article explains Java Generics in Detail With Examples: Generics are one of the important features of Java and were introduced from Java 5 onwards. A software component graph, where a node represents a component and an edge represents a use-relation between components, is widely used for analysis methods of software engineering. It claims that usability and reusability is always a tradeoff between building a heavyweight, coarse-grained software component with few dependencies (very usable) a lightweight, fine-grained software component with… Without relation reusability is not possible. (1998) suite. In total 688 classes were analyzed originating from two medium-sized java projects. To use an object of type Liquid, you must create a Liquid object with new and store the returned reference in a variable: Liquid myFavoriteBeverage = new Liquid(); The myFavoriteBeverage variable holds a reference to a Liquid object. For example, the code inside each Java class must have high internal cohesion, but be as loosely coupled as possible to the code in other Java classes. In computer science and software engineering, reusability is the use of existing assets in some form within the software product development process; these assets are products and by-products of the software development life cycle and include code, software components, test suites, designs and documentation. • Procedural languages are characterized by sequential sets of linear commands. To see how to use polymorphism in a Java program, consider the family of types shown in Figure 8-1. Visual Basic.NET and Java. Interfaces are widely used in Java applications as central design elements for modular programming to increase program reusability and to ease maintainability of software systems. jar: It is used to bundle java application into a compressed file. Chapter 3 of Meyer's Object-Oriented Software Construction (2nd edition) is a great description of these issues. We use it to launch compiled java classes and executed compiled java code.
