Synchronization

Real-life Example of Java Multithreading

Suppose you are using two tasks at a time on the computer, be it using Microsoft Word and listening to music. These two tasks are called processes. So you start typing in Word and at the same time start music app, this is called multitasking. Now you committed a mistake in a Word and spell check shows exception, this means Word is a process that is broken down into sub-processes. Now if a machine is dual-core then one process or task is been handled by one core and music is been handled by another core....

Two Ways to Implement Multithreading

Using Thread ClassUsing Runnable Interface...

Method 1: Using Thread Class

Java provides Thread class to achieve programming invoking threads thereby some major methods of thread class are shown below in the tabular format with which we deal frequently along the action performed by them....

Synchronization

It is the mechanism that bounds the access of multiple threads to share a common resource hence is suggested to be useful where only one thread at a time is granted the access to run over....

Why Synchronization is Required?

Data inconsistency issues are the primary issue where multiple threads are accessing the common memory which sometimes results in faults in order to avoid that a thread is overlooked by another thread if it fails out.Data integrityTo work with a common shared resource which is very essential in the real world such as in banking systems....

Real-life Scenario

Suppose a person is withdrawing some amount of money from the bank and at the same time the ATM card registered with the same account number is carrying on withdrawal operation by some other user. Now suppose if withdrawing some amount of money from net banking makes funds in account lesser than the amount which needed to be withdrawal or the other way. This makes the bank unsafe as more funds are debited from the account than was actually present in the account making the bank very unsafe and is not seen in daily life. So what banks do is that they only let one transaction at a time. Once it is over then another is permitted....

Conclusion

Understanding Java Multithreading is important for creating fast and efficient applications. By using multithreading, you can run multiple tasks at the same time, making your programs more responsive and powerful. Key ideas like thread synchronization, concurrent collections, and the executor framework help manage multiple threads safely. In the above article we have described all details about Java multithreading....
