Mar 19, 2025 · We can run Threads in Java by using Thread Class, which provides constructors and methods for creating and performing operations on a Thread, which extends a Thread class that can implement Runnable Interface.

Apr 16, 2025 · A thread in Java can exist in any one of the following states at any given time. A thread lies only in one of the shown states at any instant: New State; Runnable State; Blocked State; Waiting State; Timed Waiting State; Terminated State; The diagram below represents various states of a thread at any instant:

Jan 8, 2024 · In this tutorial, we learned about the life-cycle of a thread in Java. We looked at all six states defined by Thread.State enum and reproduced them with quick examples.

Thread class defines the life cycle and various states of a thread. The following diagram shows the complete life cycle of a thread. Following are the stages of the life cycle −. New − A new thread begins its life cycle in the new state. It remains in this state until the program starts the thread. It is also referred to as a born thread.

Threads allows a program to operate more efficiently by doing multiple things at the same time. Threads can be used to perform complicated tasks in the background without interrupting the main program. There are two ways to create a thread. It can be created by extending the Thread class and overriding its run() method:

Java Thread states and life cycle UML protocol state machine diagram example - new, runnable, timed waiting, waiting, blocked, terminated. This is an example of UML protocol state machine diagram showing Thread states and Thread life cycle for the Thread class in Java™. A thread is a lightweight process, the smallest unit of scheduled execution.

Thread life cycle in java: A new thread is created but not working. A thread after creation and before invocation of start () method will be in new state.

Mar 23, 2025 · Understanding the Java thread life cycle helps you design responsive and efficient multi-threaded applications. By knowing when a thread is runnable, waiting, or terminated, you can better manage concurrency and avoid common pitfalls like deadlocks and race conditions.

Aug 12, 2019 · This Java Thread tutorial helps you understand the life cycle of a thread with illustrated diagram and code example. A thread can go through various states during its life. The Thread ’s getState() method returns an enum constant that indicates current state of the thread, which falls in one of the following values:

Aug 4, 2022 · Below diagram shows different states of thread life cycle in java. We can create a thread in java and start it but how the thread states change from Runnable to Running to Blocked depends on the OS implementation of thread scheduler and java doesn’t have full control on that.
