Java Multithreading with Code Example using Runnable Interface in HINDI | Step by Step Guide for Beginners in Hindi

How to achieve Multithreading using Runnable Interface in Java?

?The easiest way to create a thread is to create a class that implements the Runnable interface. A runnable interface in Java is an interface whose instances can run as a Thread. While working with Threads, the runnable interface acts as a core element of the Java programming language. Java classes created to run Threads must implement this interface. When we extend Thread class, we can't extend any other class even we require and when we implement Runnable, we can save a space for our class to extend any other class in future or now. The most common use case of the Runnable interface is when we want only to override the run method. When a thread is started by the object of any class which is implementing Runnable, then it invokes the run method in the separately executing thread.

To use the Runnable interface to create and start a thread, you have to do the following

1.??????Create a class that implements Runnable interface.

2.??????Provide a run method in the Runnable class.

3.??????Create an instance of the Thread class and pass your Runnable object to its constructor as a parameter.

4.??????Call the Thread object's start method.

What is Multithreading?

Multithreading refers to a process of executing two or more threads simultaneously for maximum utilization of the CPU. A thread in Java is a lightweight process requiring fewer resources to create and share the process resources. Multithreading is the ability of a program or an operating system to enable more than one user at a time without requiring multiple copies of the program running on the computer. Multithreading can also handle multiple requests from the same user. Multithreading allows the execution of multiple parts of a program at the same time. These parts are known as threads and are lightweight processes available within the process. So multithreading leads to maximum utilization of the CPU by multitasking.

What is multithreading in Java?

In Java, Multithreaded applications execute two or more threads run concurrently. Hence, it is also known as Concurrency in Java. Each thread runs parallel to each other.

What are the benefits of multithreading?

1.??????multithreading Improved throughput.

2.??????Simultaneous and fully symmetric use of multiple processors for computation and I/O.

3.??????Superior application responsiveness.

4.??????multithreading Improved server responsiveness.

5.??????Program structure simplification.

6.??????Better communication.

What are daemon threads in Java?

Daemon thread in Java is a low-priority thread that runs in the background to perform tasks such as garbage collection. Daemon thread in Java is also a service provider thread that provides services to the user thread.

What are worker threads in java?

Worker thread in Java is a high-priority thread that runs in the foreground. Worker thread is a continuous parallel thread that runs and accepts messages until the time it is explicitly closed or terminated. Messages to a worker thread can be sent from the parent thread or its child worker threads.

What is thread life cycle in Java and different stages?

A thread goes through various stages in its life cycle. According to Sun, there are only 4 states in the thread life cycle in java new, runnable, non-runnable, and terminated.

What is difference between process and thread?

Process is the program under action whereas a thread is the smallest segment of instructions that can be handled independently by a scheduler.

?

What is thread synchronization?

Synchronization in java is the capability to control the access of multiple threads to any shared resource. In the Multithreading concept, multiple threads try to access the shared resources at a time to produce inconsistent results. The synchronization is necessary for reliable communication between threads.

What are the benefits of Java?

1.??????Java is relatively easy to use.

2.??????Java is an object-oriented programming language.

3.??????Java is secure.

4.??????Java is inexpensive to maintain.

5.??????Java is heavily platform-independent.

6.??????Java is a high-level programming language.

7.??????Java is super portable.

8.??????Java is stable.
