When do you use sleep and wait?
When we use the sleep() method, a thread starts after a specified time interval, unless it is interrupted. For wait(), the activation process is a bit more complicated. We can wake up the thread by calling the notify() or notifyall() methods on the monitor that is waiting.

What does wait() do in Java?
wait() The wait() method causes the current thread to wait indefinitely until another thread calls notify() on this object or notifyall().
What is thread suspend() method?
The sleep() method is used to stop the execution of the current thread (whatever is running on the system) for a specified amount of time, and after that time is over, the previously executing thread starts running again .
What is the relationship between sleep and weight?
Sleep and weight is the association between the amount of sleep an individual gets and the weight of that individual. Numerous studies have shown an association between sleep disturbances and weight gain and, more specifically, that sleep deprivation is related to being overweight.
Can we override wait() or notify() methods?
Because of this, all Java classes inherit methods from Object. The object declares three versions of the wait method, as well as notify, notify all, and get class methods. All of these methods are final and cannot be overridden.
What is the difference between the suspend and wait methods?
In short, the wait and sleep method are completely different from each other and have different use cases. Use the wait() and notify() method for inter-thread communication while using the sleep() method to introduce a small pause during thread execution.
Why always wait on a synchronized method in Java?
When a thread calls d.wait, it must hold the intrinsic lock for d; otherwise, an error is generated. Invoking wait inside a synchronized method is an easy way to acquire the intrinsic lock. When you call notify() from a t object, Java notifies a particular t.wait() method. But how does Java find and notify a particular wait method?
What is the difference between wait and sleep in Java thread?
It’s based on object locking, if you remember that every object in Java has an implicit lock, also known as a monitor.
What happens if the thread waits outside the sync block?
If Thread waits outside the sync block, then there is no monitor object and also another thread notifies to access the monitor object, so how would the thread outside the sync block know that it has been notified?
