An example of generalizing a type would be moving a method from a child to a parent class for common use by all the parent class' children, not just the original child. Another example, in the Java programming language , would be access to an object via an interface which isn't tied into a specific implementation of that interface.
Refactoring refers to a software maintenance activity where source code is modified to improve readability or improve its structure. Software is often refactored to bring it into conformance with a team's stated coding standards after its initial release. Any change that does not alter the behavior of the software can be considered refactoring.
Refactoring is usually motivated by noticing a code smell. [2] For example, the method at hand may be very long, or it may be a near duplicate of another nearby method. Once recognized, such problems can be addressed by refactoring the source code, or transforming it into a new form that behaves the same as before but that no longer "smells".
Rule of three ("Three strikes and you refactor") is a code refactoring rule of thumb to decide when similar pieces of code should be refactored to avoid duplication. It states that two instances of similar code do not require refactoring, but when similar code is used three times, it should be extracted into a new procedure.
JasperReports is an open source Java reporting tool that can write to a variety of targets, such as: screen, a printer, into PDF, [2] HTML, Microsoft Excel, RTF, ODT, comma-separated values (CSV), XSL, [2] or XML files. It can be used in Java-enabled applications, including Java EE or web applications, to generate dynamic content
The factory method design pattern solves problems such as: How can an object's subclasses redefine its subsequent and distinct implementation? The pattern involves creation of a factory method within the superclass that defers the object's creation to a subclass's factory method.
The first version of IntelliJ IDEA was released in January 2000 and was one of the first available Java IDEs with advanced code navigation and code refactoring capabilities integrated. [ 6 ] [ 7 ] In 2009, JetBrains released the source code for IntelliJ IDEA under the open-source Apache License 2.0.
