I. Priority and task Preemption
Neutrino provides a priority-driven preemptible design concept. Priority-driven means that we can assign a priority to each thread, which can obtain CPU resources based on the priority scheduling policy. If a
ObjectiveJava's thread scheduling mechanism is implemented by the JVM, which involves "thread priority" if there are several threads that you want to have a longer execution time for some threads, or if some threads allocate less execution
Preface: The graph is irrelevant, then begin to learn the knowledge of the related data structure of priority queue and heap.

Priority queue is a specific application of heap sorting.
Priority Queues are divided into the following operations:
1. INSERT (S, x) inserts element x
Priority queues are a concrete application of heap sequencing.The priority queue is divided into the following actions:1.INSERT (S,X) inserts the element x into the priority queue.2.MAXIMUM (s): Returns the element with the largest keyword in
For heap ordering, first know what is the heap data structure, heap data structure is a complete binary tree, but it has its own nature.For example, the nature of the maximum heap is:a[parent[i]]>=a[i]; that the value of each node is greater than or
Priority queuesIf we assign a number to each element to mark its priority, we might want to set a smaller number with a higher priority so that we can access the highest-priority element in a collection and find and delete it. In this way, we
The Thread's priority (Priority) tells the debugger how important the thread is. If a large number of threads are blocked and are waiting to be run, the debugger first runs the thread with the highest priority. However, this does not mean that a

In the normal queue, the order of the elements out of the team is determined by the time the element is enqueued, that is, who first team, who first out. But sometimes we want to have such a queue: who first team is not important, what is important
