29.JEGG is a framework for reducing the complexity of developing reliable multithreaded Java applications. Jegg is active object design mode.

30.IK expression is an open source (opensource), extensible (extensible), a lightweight (super lightweight) Formulation language parsing execution toolkit based on the Java language development.

IK Expression V2.0 is not dependent on any third party Java library. It is a simple jar that can be integrated into any Java application. This includes applications of Java EE applications (based on application servers), the application of java-based desktop applications, and Java Webstart methods.

IK expression was originally born to enhance the flexibility of the workflow engine, such as JBPM, for process configuration. Make it possible to change the execution logic condition as flexibly as the configuration period during the process run time. The extended IK expression can also be applied to dynamic condition configurations for a variety of conventional business systems, such as situations where graphical configuration applications are required, or scenarios that simulate formula operations for Excel spreadsheets.

31.DATE4J is a Java tool for simplifying date and time operations. You can replace Java.util.Date.

Java Third Party library ecosystem is a very broad category.

Unit Test

1.DBUnit

Dbunit is a database testing framework based on JUnit extensions. It provides a large number of classes to abstract and encapsulate database-related operations.
