What is the difference between blocked waiting and sleeping states of a process?

Difference between wait() and sleep() methods in Java. Difference between notify() and notifyAll() in Java….BLOCKED Vs WAITING States In Java :

WAITING	BLOCKED
The WAITING thread is waiting for notification from other threads.	The BLOCKED thread is waiting for other thread to release the lock.

What are the different states of thread in OS?

In an operating system, a process may have any number of threads, which are tasks within a given process. A thread state diagram highlights different states of a thread, which are new, runnable, blocked, and terminated.

In which state the thread is ready for execution and is waiting for the availability of the processor?

runnable state
In runnable state, thread is ready for execution and is waiting for availability of the processor (CPU time). That is, thread has joined queue (line) of threads that are waiting for execution.

What is thread blocking?

When we say that a thread blocks, we mean that the method (operation) that the thread calls, put or take, is blocking the thread from proceeding to execute the next line of code until some condition is met — the queue is not full or queue is not empty.

What is the difference between waiting and blocked state of a thread?

In the BLOCKED state, a thread is about to enter a synchronized block, but there is another thread currently running inside a synchronized block on the same object. The first thread must then wait for the second thread to exit its block. In the WAITING state, a thread is waiting for a signal from another thread.

What is difference between thread sleep and thread wait?

It tells the calling thread (a.k.a Current Thread) to wait until another thread invoke’s the notify() or notifyAll() method for this object, The thread waits until it reobtains the ownership of the monitor and Resume’s Execution….Difference between wait and sleep in Java.

Wait()	Sleep()
Wait() is not a static method.	Sleep() is a static method.

What are the differences between ready state and running state?

The process is created while in the new state. In the running or waiting state, the process is executing or waiting for an event to occur, respectively. The ready state occurs when the process is ready and waiting to be assigned to a processor and should not be confused with the waiting state mentioned earlier.

When can a thread block other threads?

Blocking calls in one thread should not affect other threads. If the blocked thread locks a mutex prior to entering the blocked call and the second thread attempts to lock the same mutex, then they the second thread would need to wait for the blocking call to finish and for the first thread to release the lock.

Which thread method is used to wait until it terminates?

Explanation: join() method of Thread class waits for thread being called to finish or terminate, but here we have no condition which can terminate the thread, hence code ‘t.

What is the difference between blocked and wait in threading?

Blocked- Your thread is in runnable state of thread life cycle and trying to obtain object lock. Wait- Your thread is in waiting state of thread life cycle and waiting for notify signal to come in runnable state of thread.

What does the blocked state mean in a thread?

The BLOCKED state means waiting for an object’s monitor. This often happens when a synchronized method or statement is used. The thread is waiting for access to synchronized code, or to do any other action that requires owning the object’s monitor.

What is the difference between blocked and waiting state in Java?

BLOCKED – this state represents a thread which has been blocked and is waiting for a moniotor to enter/re-enter a synchronized block/method. A thread gets into this state after calling Object.wait method. WAITING – this state represnts a thread in the waiting state and this wait is over only when some other thread performs some appropriate action.

What does it mean when a thread is in waiting state?

Titbit: A Thread will enter into WAITING state when it’s calling one of the following methods: Thread that has called Object.wait () on an object is in WAITING state until another thread to call Object.notify () or Object.notifyAll () on that object. A thread that has called Thread.join () is in WAITING state for a specified thread to terminate.
