Code refactoring activities are secured with software intelligence when using tools and techniques providing data about algorithms and sequences of code execution. [10] Providing a comprehensible format for the inner-state of software system structure, data models, and intra-components dependencies is a critical element to form a high-level ...
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
JCov is the tool which has been developed and used with Sun JDK (and later Oracle JDK) from the very beginning of Java: from the version 1.1. JCov is capable of measuring and reporting Java code coverage. JCov is distributed under the terms of the GNU General Public License (version 2, with the Classpath Exception). JCov has become open-source ...
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. The rule was popularised by Martin Fowler in Refactoring [1] and attributed to Don Roberts. Duplication is considered a bad practice in programming because it makes the code harder to ...
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.
Type generalization is a technique commonly used in refactoring.The idea is to draw on the benefits of object-orientation and make more-generalized types, thus enabling more code sharing, leading to better maintainability as there is less code to write.
In software engineering, the Extract Class refactoring is applied when a class becomes overweight with too many methods and its purpose becomes unclear. Extract Class refactoring involves creating a new class and moving methods and/or data to the new class.
This example uses a String as the state, which is an immutable object in Java. In real-life scenarios the state will almost always be a mutable object, in which case a copy of the state must be made. It must be said that the implementation shown has a drawback: it declares an internal class.
