How to analyze the definition and code of Java task queue? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Java task queue requires us to study in detail, of course, we also need to pay attention to the learning of relevant information in the continuous use of it. Let's first take a look at the specific application of TaskQueue (Task queue). Let's study it in detail.

There may be many tasks to perform at the same time, but the program can only perform a certain number of tasks at the same time. What if the number of tasks that need to be performed exceeds the number of tasks the program can handle? There are rules for which tasks to perform first and which tasks to perform later.

The TaskQueue class defines one of these rules, which uses the FIFO (first-in, first-out, English name First In First Out) approach, that is, in the order in which the tasks arrive. The definition of the TaskQueue class.

The Java task queue code is as follows:

Import java.util.Iterator; import java.util.LinkedList; import java.util.List; public class TaskQueue {private List queue = new LinkedList (); / / add a task public synchronized void addTask (Task task) {if (task! = null) {queue.add (task) Delete public synchronized void finishTask (Task task) {if (task! = null) {task.setState (Task.State.FINISHED); queue.remove (task);}} / / get a pending task public synchronized Task getTask () {Iterator it = queue.iterator (); Task task; while (it.hasNext ()) {task = it.next () / / find a new task if (Task.State.NEW.equals (task.getState () {/ / set the task status to running task.setState (Task.State.RUNNING); return task;}} return null;}} import java.util.Iterator; import java.util.LinkedList; import java.util.List; public class TaskQueue {private List queue = new LinkedList () / / add a task public synchronized void addTask (Task task) {if (task! = null) {queue.add (task);}} / / remove it from the task queue after completing the task (Task task) {if (task! = null) {task.setState (Task.State.FINISHED); queue.remove (task) }} / / get a pending task public synchronized Task getTask () {Iterator it = queue.iterator (); Task task; while (it.hasNext ()) {task = it.next (); / / find a new task if (Task.State.NEW.equals (task.getState () {/ / set the task status to running task.setState (Task.State.RUNNING); return task;}} return null }} this is the answer to the question on how to define the Java task queue and analyze the code.
