The ThreadGroup class in Java is a part of the java.lang package that provides methods for managing groups of threads. A thread group represents a set of threads that can be managed together, allowing for operations to be performed on all threads in the group simultaneously.

This guide covers various methods available in the ThreadGroup class. Each method is described in simple terms to help beginners understand how to use them. These methods enable the management of thread groups, such as counting active threads, interrupting all threads in a group, and more.

For more detailed information, please refer to the official Java SE Documentation.
