Concept of Java Multithreading With Interview Questions

Java is a popular and dynamic programming language used by developers. It ranks top among the list of most sought and preferred language by professional programmers. Java being an object-oriented programming language, it is easy to create different objects as well as manipulate the existing ones for making them better. One is allowed to reuse the codes and modular programs.

Another factor which makes it stand out in comparison to other programming language is its characteristic of Multithreading. So, what exactly is multithreading program in java and how is it useful in coding and building apps. Here in this article, we would delve deeper into the topic and know its various parameters.

What is Java Multithreading?

The term multithreading in java is one of the key features in Java programming. Multithreading opportune programmers in creating a network and building visual programming. This characteristic of Java allows a particular program in functioning different tasks all together at the same time innate to the program. When two programmes are running simultaneously, each program containing a part or more is called a java thread. However, no two threads perform the same function and have their separate line of execution.

Java happens to be one of the core programming language used for the execution of processes as it removes the constraints of developing high-end applications. More and more companies prefer programmers who have a good hold on Java Multithreading and the java thread interview questions revolve around this aspect. Some of the questions are as follows:

What is a Java Thread Cycle?

The thread life cycle in java is defined as the time taken to synchronize one thread into another. The different stages of thread life cycle include:

New – In this stage, a new thread starts its new life cycle. The thread would continue to remain in the same state until the program starts its execution. This stage of java thread example is known as a born thread.

Runnable – Once the thread is started it is called runnable thread which is ready to execute its task. Thus, multiple threads lead to a java thread pool, which has different threads performing separate functions at the same time.

Waiting – This stage is where the present thread transits in waiting for other thread to perform its task. The thread in waiting will not continue to execute unless it doesn’t receive a signal from the other thread.

Timed Waiting – Sometimes the running thread can also transit into timed waiting for a specified time interval. The thread will continue to execute work only once the threaded interval expires. This helps in process synchronization and to run multiple threads simultaneously without hassle. This is executed using java timer that blocks other threads from functioning at the same time and the thread does not run unless the other doesn’t end.

Terminated – This is the last stage of the thread when the thread completes its entire execution.

What is the meaning of synchronizing in java?

The word synchronize meaning or synchronised meaning in Java is a keyword used to describe the process. The word denotes that no two threads execute a synchronized method requiring the same lock concurrently and simultaneously.

What is Java Concurrency?

With the view of running the program in a smoother way, Java Virtual Machine is designed to support the concurrent programming, which works for executing the threads. The term java concurrency is a java multithreading example that aids the objects and resources to get accessed by its own path of execution and doesn’t hinder with the simultaneous processing in order to synchronise the entire process.

For this, the programmer uses different hash maps. Some of the examples of java hashmap example include () for remove, { for public class // for creating and populating the hash map, and much more. This allows the programmer in giving a command to the script for building or removing threads.

As Java renders programmers a medium for building apps without much complexity, it is the most preferred tool for creation of applications. In order to learn the entire process and the steps involved one can resort to thejava thread tutorial available on the internet.
