Here I am listing down most of the important java multithreading interview questions from interview perspective, but you should have good knowledge on java threads to deal with follow up questions.
Deadlock in java is a programming situation where two or more threads are blocked forever. Java deadlock situation arises with at least two threads and two or more resources. Here I have written a simple program that will cause java deadlock scenario and then we will see how to analyze it. Deadlock in Java Let’s have a look at a simple program where I will create deadlock in java threads.
The Object class in java contains three final methods that allows threads to communicate about the lock status of a resource. These methods are wait (), notify () and notifyAll (). So today we will look into wait, notify and notifyAll in java program. wait, notify and notifyAll in Java The current thread which invokes these methods on any object should have the object monitor else it throws ...
Java Thread Example Every java application has at least one thread - main thread. Although there are so many other java threads running in background like memory management, system management, signal processing etc. But from application point of view - main is the first java thread and we can create multiple threads from it.
Java thread pool manages the pool of worker threads. It contains a queue that keeps tasks waiting to get executed. We can use ThreadPoolExecutor to create thread pool in Java. Java thread pool manages the collection of Runnable threads. The worker threads execute Runnable threads from the queue. java.util.concurrent.Executors provide factory and support methods for java.util.concurrent ...
Understanding Thread Life Cycle in Java and Thread States are very important when you are working with Threads and programming for multithreaded environment. From our last tutorial, we can create a java thread class by implementing Runnable interface or by extending Thread class, but to start a java thread, we first have to create the Thread object and call it’s start () method to execute ...
Thread Safe Singleton in Java In general, we follow the below steps to create a singleton class: Create the private constructor to avoid any new object creation with new operator. Declare a private static instance of the same class. Provide a public static method that will return the singleton class instance variable.
