Thread state transitions in Java:　　Note: Start execution immediately after start, just ready (the CPU may be running other threads)."Note": Only after the CPU is dispatched, the thread will start executing, and when the CPU is allocated to your time slice, and back to the ready state, continue to wait in line.The basic method of threading control:　　IsAlive (): Determine if the thread is still alive, start, and before the termination is alive;GetPriori

the boot, which is just a reference to the calculation priority when the OS starts the thread. The OS will also see if the current thread is hogging the CPU for a long time, and if so, the OS will moderately increase the priority of other "hungry" threads. Forced suspend for those threads that have been hogging the CPU for a long time. Making this setting simply increases the chance that the thread will be executed in some way. In fact, those long-term occupation of the CPU thread is not a sing

between the sleep method and the Wait method in Java? AnswerWhile both are used to pause the currently running thread, sleep () is actually just a short pause because it does not release the lock, and wait () means that the condition waits, which is why the method is releasing the lock because the other waiting thread can get to the lock when the condition is met.15) What are immutable objects (immutable object)? How do I create an immutable object in Java? AnswerImmutable objects means that on
