Thread Life

A thread is a lightweight process that can execute concurrently with other threads. Threads share resources, such as memory and files, but they have their own execution paths.

Key Concepts:

Thread creation: The process of starting a new thread.
Thread execution: The actual code execution within a thread.
Thread state: The internal information and data of a thread.
Synchronization: Mechanism used to ensure safe access to shared resources.
Synchronization primitives: Objects used to control access to shared resources, such as locks and semaphores.

Life Cycle:

Thread creation: A new thread is created and starts running in the thread pool.
Initialization: The thread initializes its state, including a unique ID, name, and stack pointer.
Start method: The thread calls the start() method to begin its execution.
Execution: The thread's execution method is called.
Termination: When the thread finishes its execution, it stops and is removed from the thread pool.

Example:

java

// Create a new thread

Thread thread = new Thread(() -> {

// Code to execute in the thread

});

// Start the thread

thread.start();

Benefits of Threads:

Concurrency: Threads allow multiple threads to execute concurrently, improving application performance.
Efficiency: Threads avoid blocking other threads, reducing waiting time.
Parallelism: Threads can execute tasks in parallel, improving performance for resource-intensive tasks.

Note:

Threads share the same memory space as the thread pool.
Different threads have their own stack but share the same heap memory as the thread pool.
Synchronization is essential to prevent data corruption and ensure safe access to shared resources
