The NoClassDefFoundError is a runtime error in Java that occurs if the Java Virtual Machine (JVM) or a ClassLoader instance attempts to load the definition of a class that could not be found. The class definition exists at compile-time but is not available at runtime.

A Java stack trace is displayed when an error or exception occurs. The stack trace, also called a backtrace, consists of a collection of stack records, which store an application's movement during its execution. The stack trace includes information about program subroutines and can be used to debug or troubleshoot and is often used to create log files. These exceptions could be custom (defined by the user) or built-in.

API testing is more important than ever.

Mocking APIs is an increasingly popular trend, with more and more developers seeing the advantages of mocking dependencies rather than spinning up actual duplicates of resources. On a high-level, a mock API means that you have a service that returns static data, which in turn is based on a real API.

Data visualization tools help turn complex data into intuitive charts, and enable faster understanding of key insights from large datasets.
