Oracle Jdeveloper

Oracle JDeveloper is a free integrated development environment that simplifies the development of Java-based applications addressing every step of the application lifecycle. JDeveloper offers complete end-to-end development for Oracle's platform and Oracle's applications.

Oracle JDeveloper and Oracle Application Developer Framework 12.2.1.1 is a new release following 12.2.1.0 and is part of the larger Fusion Middleware product suite release of 12.2.1.1. With this latest release users can convert lambda to anonymous inner class. This is the corollary refactoring to converting an anonymous inner class to use a lambda expression.

In addition, recent license changes to JUnit, have freed Oracle from shipping the JUnit libraries in a separate extension bundle. The features for adding, editing and running unit tests are now included in the JDeveloper download. Oracle JDeveloper now comes with Data Visualization Enhancements. For instance, Picto Chart uses discrete icons to visualize an absolute number or relative sizes. It is extensively used in infographics as a more interesting and effective way to present numerical information than traditional tables and lists.

On the other hand, Tag Cloud provides visual representation for text data, typically used to visualize free form text or tag metadata for a website. Oracle has also added new chart types like the Stock Chart which is useful for displaying information about a stock on a time axis. Unique to stock charts is the candlestick series which allows for displaying open, close, high, low information for the stock price. Range area and range bar charts have also been availed to help visualize data sets with varying low/high values.
