What is Multithreading in Java With Examples

Do you know what is multithreading in Java? Have you ever thought about what can be an example of multithreading in Java? Let us try to understand multithreading in Java with example.

But before we start to know multithreading in JavaScript, let us try to find out the process of multithreading from an example of our daily life. This will help to understand what is multithreading in Java in a better manner.

Let us try to assume one scenario.

Suppose, you have a lot of assignments to complete. Your teacher provided a lot of tasks to do during your winter vacation. Now, one beautiful day, you start working on those assignments. Suddenly, your mother asked you to bring some stuff from the market. So, you stopped your work & move to the market to bring that product.

Now, after some time, your mother again asked to bring some other elements to form the market. You again stopped your work & followed the order. Again sometime later, your mother asked you to bring some other stuff from the market. What will you do in such a case?

You will request to mother to make a list of all the products that are needed to bring from the market at a time. Going to the market every time is wasting your time to complete the assignment. So, you are trying to reduce your effort & time consumption.

The same thing goes for multithreading in JavaScript. Multithreading JavaScript helps to execute the same task at the same time. Multithreading in JavaScript helps a lot to do the same task at the same time. It reduces time & space consumption.

Let us try to know more about this. Hence, it will help to clear the understanding regarding multithreading JavaScript.

What Is Multithreading In Java? Read Below

 

Multithreading JavaScript is a process where a program can able to execute different work at the same time. Threads are the light-weighted part of the program. This is like the program inside of a program. Thread is particularly used when during the program, some other tasks need to be executed or performed. An example of multithreading in Java is essential to know about it.

Threads are being used in Object-Oriented Programming Languages. As the thread feature is only provided by those programming languages. Java is one of them. Multithreading in Java helps a lot in animation & gaming purposes. In both these cases, while programming is running, the user can able to do other operations as well. This feature only provides by the multithreading option.

Multithreading operation also requires small memory space. The same memory space is being used again & again. This reduces the memory exhaustion problem in the programming languages. Using multithreading will help to utilize the CPU at its best performance. For all those reasons, multithreading in Java is very important. Multithreading in Java with examples helps a lot to understand the topic.

 

 

What Are The Methods For Multithreading In Java? Get To Know

 

There are mainly two methods for multithreading in Java. An example of multithreading in Java will help you to understand those methods properly. Those two methods are:

  1. Using Thread Class
  2. Using Runnable Interface

Let us try to know about these methods one by one in a brief to know about multithreading in Java.

Let us try to implement the above methods with an example. That will help to understand multithreading in Java with example.

 

 

Multithreading In Java Using Thread Class:

 

Here, at first, we need to declare another class that will extend the Thread class. Now, inside of that, we need to write the run() method. The run() is the in-built method for multithreading In Java. The run() method helps to indicate the start of the thread. Inside the run() method, we have written some statements.

Now, inside the main() method, we need to make an object of the declared class. Using that object, we need to start the thread. The start() is the in-built method of the thread. This in-built method initialized the thread. This means this method will start executing the thread.

 

Example:

 

class CodingZap extends Thread {

    public void run(){

            // Displaying The Thread Which Is Running

            System.out.println(Thread.currentThread().getId()+ ": Thread Is Executing");

    }}

public class Main{

            public static void main(String[] args) {

                        int n = 5; // Thread Numbers

                         for (int i = 0; i < n; i++) {

                         CodingZap obj = new CodingZap(); // Creating Object

                         obj.start();}}}

 

 

Let us try to find out the output of the above code. This will help to understand multithreading in JavaScript.

 

Output:

multithreading in java using thread class output

 

Multithreading In Java Using Runnable Interface:

 

Here again, we need to declare another class that will implement the Runnable function. Runnable is another step of the thread. Like thread class extension, this is also used to implement thread. Now, inside of that, we need to write the run() method. Inside the run() method, we have written some statements.

Now, inside the main() method, we need to make an object of the declared class but in a different manner. We need to first create the object of the thread. Now, we need to cast the declared class object inside of that. Using that object, we need to start the thread. The start() is the in-built method of the thread. This in-built method initialized the thread. This means this method will start executing the thread.

 

Example:

 

class CodingZap implements Runnable {

    public void run(){

            // Displaying The Thread Which Is Running

            System.out.println(Thread.currentThread().getId()+ ": Thread Is Executing");

    }}

public class Main{

            public static void main(String[] args) {

                        int n = 5; // Thread Numbers

                         for (int i = 0; i < n; i++) {

                         Thread obj = new Thread(new CodingZap()); // Creating Object

                         obj.start();}}}

Let us try to find out the output of the above code. This will help to understand the example of multithreading in Java.

Output:

Multithreading In Java Using Runnable Interface Output

 

 

Conclusion:

 

As we saw, multithreading in Java is a very important topic.

We have to always remember what is multithreading in Java. Multithreading JavaScript helps us to solve difficult problems in the future.

Multithreading in Java with example is a very important sub-topic of this content. It is advisable to clear the basis of the Java programming language. This will help a lot in the future.
