What is a Thread in Java?
A thread in Java is the direction or path that is taken while a program is being executed. Generally, all the programs have at least one thread, known as the main thread, that is provided by the JVM or Java Virtual Machine at the starting of the program’s execution. At this point, when the main thread is provided, the main() method is invoked by the main thread.


A thread is critical in the program because it enables multiple operations to take place within a single method. Each thread in the program often has its own program counter, stack, and local variable.


Creating a Thread in Java

A thread in Java can be created in the following two ways:

Extending java.lang.Thread class
Implementing Runnable interface


There are basically 4 stages in the lifecycle of a thread.

New
Runnable
Running
Blocked (Non-runnable state)
Dead


Java Thread Priorities.

The number of services assigned to a given thread is referred to as its priority. Any thread generated in the JVM is given a priority. The priority scale runs from 1 to 10.


1 is known as the lowest priority.
5 is known as standard priority.
10 represents the highest level of priority.
