Java multithreaded execution tasks, handling security issues for shared member variables

In order to avoid repetitive execution of tasks in Java multithreaded execution, shared member variables can be processed through the Synchronized keyword, with the following code:

 //Multithreading task Method　　
Private voidProcessmultitask (FinalList<logstattask> list,intThreadCount)throwsException {
　　　　　Process Task List based on number of threads set
　　　　  for(inti = 0; i < ThreadCount; i++) {Taskthread thread=Newtaskthread (list);        Thread.Start (); }    }
　　//Task Processing thread class classTaskthreadextendsThread {PrivateList<logstattask> taskList =NULL;
　　　　//Create constructors based on thread class member variables  PublicTaskthread (list<logstattask>taskList) {            Super();  This. taskList =taskList; }         Public voidrun () { while(true) {Logstattask task;
　　　　　　　　　 //Lock the Tasklist Task table object to ensure that only one thread is manipulating it synchronized(taskList) {
　　　　　　　　　　　　//If the task list is empty, exit execution if(Collectionutils.isempty (taskList)) { Break; }
　　　　　　　　　　　　//Remove a pending task from the Task task list and remove  the task from the Tasks table= Tasklist.remove (0); } //Release the lock on Tasklist so that other threads can operate on it, and this thread will handle it according to the task accordingly             }        }    }
