Should I sleep or wait?

In general, we should use sleep() for controlling execution time of one thread and wait() for multi-thread-synchronization. Naturally, there's a lot more to explore – after understanding the basics well. As always, you can check out the examples provided in this article over on GitHub.

What is sleep () method?

The sleep() method of Thread class is used to sleep a thread for the specified amount of time.

What happens when thread's sleep () method is called *?

Sleep() - This method causes the currently executing thread to sleep (temporarily cease execution) for the specified number of milliseconds. The thread does not lose ownership of any monitors. It sends the current thread into the “Not Runnable” state for a specified amount of time.

Why thread sleep is used?

Thread. sleep causes the current thread to suspend execution for a specified period. This is an efficient means of making processor time available to the other threads of an application or other applications that might be running on a computer system.

Is sleep a blocking call?

sleep is blocking. We now understand that we cannot use Thread. sleep – it blocks the thread. This makes it unusable until it resumes, preventing us from running 2 tasks concurrently.

What type of wait is thread sleep?

Selenium has overcome the problems provided by Thread. sleep() and have come up with two Selenium waits for page load. One of which is Implicit wait which allows you to halt the WebDriver for a particular period of time until the WebDriver locates a desired element on the web page.

What is join () in Java?

lang. Thread class provides the join() method which allows one thread to wait until another thread completes its execution. If t is a Thread object whose thread is currently executing, then t. join() will make sure that t is terminated before the next instruction is executed by the program.

What is wait () in Java?

wait() causes current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. In other words, this method behaves exactly as if it simply performs the call wait(0). This method should only be called by a thread that is the owner of this object's monitor. ...

What is deadlock in Java?

Deadlock describes a situation where two or more threads are blocked forever, waiting for each other. ... 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.

What does float a 35 0 return mean?

10) What does the expression float a = 35 / 0 return? Explanation: In Java, whenever we divide any number (double, float, and long except integer) by zero, it results in infinity. ... But on dividing an integer by zero, it throws a runtime exception, i.e., java.lang.ArithmeticException.

Why is thread sleep bad?

If given a wait of 5000 Milliseconds(5 seconds) and an element just take just 1-2 seconds to load, script will still wait for another 3 seconds which is bad as it is unnecessarily increasing the execution time. So thread. sleep() increases the execution time in cases where elements are loaded in no due time.

Is it possible to start a thread twice?

No. After starting a thread, it can never be started again. In such case, thread will run once but for second time, it will throw exception. ...
