1 being the lowest and 5 being the default. If you specify a priority that is out of range, then an IllegalArgumentException exception thrown. Some thread priorities are static member variables ofjava.lang.Thread class. These include MIN_PRIORITY, NORM_PRIORITY, and MAX_...
Inside getCalendar(), the call to calendarRef.get() will always operate on our thread-private "instance" of the variable, and we don't need any synchronization.This example uses the Java 5 generics feature: we declare ThreadLocal as 'containing' Calendar objects, so that the subsequent get...
ThreadLocal in Java is another way to achievethread-safetyapart from writing immutable classes. If you have been writing multi-threaded or concurrent code in Java then you must be familiar with cost of synchronization or locking which can greatly affect Scalability of application, but there is no...

Thread States The following diagram illustrates the various states that a Java thread can be in at any point during its life and which method calls cause a transition to another state. This diagram is not a complete finite state diagram, but rather an overview of the more interesting and comm...
This Selenium Java tutorial discusses Thread.sleep() in Java to pause the code execution for some time and best practices of using Selenium’s implicit, explicit and fluent waits in the code for saving the time in test automation code execution.
We have already discussed a bit about synchronization when we shared the tutorial on Vector vs ArrayList. As we are aware that ArrayList is non-synchronized and should not be used in multi-thread environment without explicit synchronization. This post is
Java ThreadLocal is used to create thread local variables. We know that all threads of an Object share it’s variables, so the variable is not thread safe. We can use synchronization for thread safety but if we want to avoid synchronization, we can useThreadLocalvariables. ...
In Java, thesynchronizedblock uses an object to achieve thread synchronization.Each object has an intrinsic lock.Only the thread that acquires the lock first is allowed to execute thesynchronizedblock. Here, we created two references,IS_NOT_FULLandIS_NOT_EMPTY, to use for synchronization. As the...
