Also, java is the first programming language that introduced the concept of multithreading. The primary function of multithreading is to simultaneously run or execute multiple tasks. These tasks are represented as threads in a java program and have a separate execution path.
Thread in java is an independent path of execution that is used to run two tasks in parallel. When two threads run in parallel that is called multithreading in java.
Importance of multi-threading is huge in java space and correct understanding of threading concept is very important for any java developer. Skill to find and avoid concurrency issues like thread-safety, deadlock and race conditions are getting increasingly important with programming on multi core processors.
For example, i have written a program in java which implements a certain protocol. In this protocol the two parties send and receive to each other thousands of messages, they encrypt those messages and resend them (and receive them) again and again. As expected, multithreading is key when you deal in the scale of thousands.

Java allows to write a program where more than one processes can be executed concurrently within the single program. Java's threads are often referred to as light weight threads, which means that they run in the same memory space.
Java will benefit from multiple cores, if the os distribute threads over the available processors. Jvm itself do not do anything special to get its threads scheduled evenly across multiple cores. A few things to keep in mind: while implementing parallel algorithms, it might be better to spawn as many threads as there are cores.

Unlike many other computer languages, java provides built-in support for multithreaded programming. A multithreaded program contains two or more parts that can run concurrently.
Therefore, it is desirable to write a few classes that handle multithreading that can be reused. In fact, the classes that i wrote for web crawling originally were reused exactly as they are for a machine learning program. Java provides easy-to-use classes for both multithreading and handling of lists.
Multithreading in java is a process of executing multiple threads simultaneously. Thread is basically a lightweight sub-process, a smallest unit of processing. Multiprocessing and multithreading, both are used to achieve multitasking. But we use multithreading than multiprocessing because threads share a common memory area.

Threads and concurrent programming with processors packing more cores than ever, concurrent programming is at the forefront to harness them efficiently. However, the fact remains that concurrent programs are much more difficult to design, write, test, and maintain.
In the java programming language, concurrent programming is mostly concerned with threads. A computer system normally has many active processes and threads. This is true even in systems that only have a single execution core, and thus only have one thread actually executing at any given moment.
These days when there are multi core processors are easily available programmers should defiantly take advantage of parallel programming for scalable and highly performing and responsive application. Multi threading programming comes with certain complexities and sometimes difficult to program.

Multithreading means doing things simultaneously, in parallel. Threads are units of code that can be executed at the same time. They are sometimes called lightweight processes, although, in fact, a thread is executed within a process (and every process has, at least, one thread, the main thread).
Java divides thread into 2 types: normal thread and deamon thread. In a program, normal threads and deamon thread run parallel each other. When all normal thread finish, all deamon threads will be ending.

When single thread is taking long time to complete a computational activity, you should break it into small tasks and use multi-threading to reduce computation time. You can see lot of use cases for multi threading in your project.
A java multithreaded program may suffer from the deadlock condition because the synchronized keyword causes the executing thread to block while waiting for the lock, or monitor, associated with the specified object.
Objects and resources can be accessed by many separate threads; each thread has its own path of execution but can potentially access any object in the program.
A multithreaded program contains two or more parts that can run concurrently. Each part of such a program is called thread and each thread defines a separate path of execution. Next concept in this java thread blog is integral to the concept threads and multithreading.

As recognized, adventure as well as experience not quite lesson, amusement, as capably.
Java author mentions: threads can simplify the development of complex systems by turning complicated asynchronous code into simpler straight-line code. Again the book says: threads make it easier to model how humans work and interact, by turning asynchronous workflows into mostly sequential ones.
