WFindBugs is an open-source static code analyser created by Bill Pugh and David Hovemeyer which detects possible bugs in Java programs. Potential errors are classified in four ranks: (i) scariest, (ii) scary, (iii) troubling and (iv) of concern. This is a hint to the developer about their possible impact or severity. FindBugs operates on Java bytecode, rather than source code. The software is distributed as a stand-alone GUI application. There are also plug-ins available for Eclipse, NetBeans, IntelliJ IDEA, Gradle, Hudson, Maven, Bamboo and Jenkins.
WGradle is a build automation tool for multi-language software development. It controls the development process in the tasks of compilation and packaging to testing, deployment, and publishing. Supported languages include Java, C/C++, JavaScript.

WHudson was a continuous integration (CI) tool written in Java, which runs in a servlet container such as Apache Tomcat or the GlassFish application server. It supports SCM tools including CVS, Subversion, Git, Perforce, Clearcase and RTC, and can execute Apache Ant and Apache Maven based projects, as well as arbitrary shell scripts and Windows batch commands. The primary developer of Hudson was Kohsuke Kawaguchi, who worked for Sun Microsystems at the time. Released under the MIT License, Hudson is free software.
WIntelliJ IDEA is an integrated development environment (IDE) written in Java for developing computer software. It is developed by JetBrains, and is available as an Apache 2 Licensed community edition, and in a proprietary commercial edition. Both can be used for commercial development.
WJava Virtual Machine Tool Interface was introduced in J2SE 5.0 (Tiger). This interface allows a program to inspect the state and to control the execution of applications running in the Java Virtual Machine (JVM). JVMTI is designed to provide an Application Programming Interface (API) for the development of tools that need access to the state of the JVM. Examples for such tools are debuggers or profilers.
WJBuilder is a discontinued integrated development environment (IDE) for the programming language Java from Embarcadero Technologies. Originally developed by Borland, JBuilder was spun off with CodeGear which was eventually purchased by Embarcadero Technologies in 2008.
WJCreator is a Java IDE created by Xinox Software. Its interface is similar to that of Microsoft's Visual Studio. Because it is programmed entirely in C++,, Xinox Software has asserted that JCreator is faster than competing Java-based Java IDEs.
WJDeveloper is a freeware IDE supplied by Oracle Corporation. It offers features for development in Java, XML, SQL and PL/SQL, HTML, JavaScript, BPEL and PHP. JDeveloper covers the full development lifecycle from design through coding, debugging, optimization and profiling to deploying.
