Difference between a Thread and an Executor in Java

Even though both Thread and Executor, both are used to execute some code in parallel, there are some key differences between them. The main difference between a Thread and an Executor in Java is that it later provides a thread pool in Java. Along with several concurrency utilities like CountDownLatch, CyclicBarrier, Semaphore, FutureTask, Callable interface, and Conditions, JDK 5 also introduced a built-in thread pool, which provides a set of working threads to run your code in parallel. Since creating, starting, and running a thread is a time-consuming and expensive operation, many Java applications create a spool of thread at start-up and leverage that for executing the task in parallel until Java introduced the built-in thread pool.

This is one of the good multi-threading questions for experienced Java programmers, mostly asked in Investment Banks like Barclays, Deutsche Bank, or Citibank.

The core interface in Java 1.5's Executor framework is the Executor interface which defines the execute(Runnable task) method, whose primary purpose is to separate the task from its execution.

This is one of the reasons I always encourage Java developers to give/take regular interviews, just to update your knowledge.

Difference between Executor, ExecutorService and Executers class in Java

All three classes Executor, ExecutorService, and Executors are part of Java's Executor framework which provides thread pool facilities to Java applications. Since the creation and management of Threads are expensive and the operating system also imposes restrictions on how many Threads an application can spawn, it's a good idea is to use a pool of threads to execute tasks in parallel, instead of creating a new thread every time a request comes in. This not only improves the response time of the application but also prevent resource exhaustion errors like "java.lang.OutOfMemoryError: unable to create new native thread".

Maven Eclipse plugin M2Eclipse issues after updating passwords

Most of the time these are compilation errors that are caused because maven is not able to connect to remote maven central repository, even though you have updated password in settings.xml in the maven installation folder like C:\apache-maven-2.2.1\conf\settings.xml

ThreadLocal in Java - Example Program and Tutorial

ThreadLocal in Java is another way to achieve thread-safety apart from writing immutable classes. If you have been writing multi-threaded or concurrent code in Java then you must be familiar with the cost of synchronization or locking which can greatly affect the Scalability of application, but there is no choice other than synchronizing if you are sharing objects between multiple threads. ThreadLocal in Java is a different way to achieve thread-safety, it doesn't address synchronization requirement, instead, it eliminates sharing by providing an explicit copy of Object to each thread. Since Object is no more shared there is no requirement of Synchronization which can improve scalability and performance of the application.

Inter Thread Communication in Java using Wait Notify Example

Wait and notify methods in Java are used for inter-thread communication i.e. if one thread wants to tell something to another thread, it uses notify() and notifyAll() method of java.lang.Object. A classical example of the wait and notify method is a Producer-Consumer design pattern, where One thread produces and put something on the shared bucket, and then tell the other thread that there is an item for your interest in a shared object, consumer thread than pick than item and do his job, without the wait() and notify(), consumer thread needs to be busy checking, even if there is no change in the state of the shared object.
