How Multithread Work In Java:-

Concept Of Multithreading In Java:-

Multithreading is a process in whichmultiple threads or tasks run concurrently in a single program or application. It allows a program to perform multiple tasks at the same time by distributing the tasks among multiple threads. 

Multithreading in Java is a process of executing multiple threads simultaneously. A thread is a lightweight sub-process, a smallest unit of processing. Multiprocessing and multithreading, both are used to achieve multitasking. However, we use multithreading than multiprocessing because threads share a common memory area. Threads are independent and can be used to perform different tasks simultaneously.

Creating a thread in Java is done by implementing the Runnable interface. The Runnable interface defines a single method, run(), which contains the code that is executed by the thread. The Runnable interface must be implemented by any class whose instances are intended to be executed by a thread. The class must define a method of no arguments called run.

Threads can be created in two ways in Java:

1. By extending the Thread class

2. By implementing the Runnable interface

The advantages of multithreading include:

1. Improved performance – Threads allow multiple tasks to be performed at the same time. This improves performance because tasks can be done in parallel, instead of sequentially.

2. Resource sharing – Threads share the same address space, which allows them to share information and resources.

3. Responsiveness – Multithreading allows a program to remain responsive to input by delegating some tasks to background threads.

4. Low resource consumption – Threads have a much smaller memory footprint than processes, making them ideal for low-resource applications.

5. Scalability – Threads are lightweight and can easily be scaled up or down, depending on the needs of the application.

The main disadvantage of multithreading is that it can increase the complexity of the program, making it more difficult to debug and maintain. Also, synchronization issues can arise if multiple threads attempt to access and modify shared data at the same time.

Overall, multithreading is an important concept in Java that enables improved performance and resource sharing in applications. It can be used to perform multiple tasks concurrently and is an essential tool for developing high-performance, scalable applications.

4.)Syntax Of Multithreading:-

//Creating a thread:

Thread thread = new Thread(); //Starting a thread: thread.start(); //Stopping a thread: thread.stop(); //Pausing a thread: thread.suspend(); //Resuming a thread: thread.resume(); //Synchronizing a thread: synchronized(object) { // code } //Prioritizing a thread: thread.setPriority(int priority);
