How does abstract classes behave in multithreaded code?

Abstract classes in Java serve as a blueprint for other classes and can be used in multithreaded environments just like any other Java class. However, it's crucial to understand how to manage shared resources properly to avoid issues such as race conditions, deadlocks, and data inconsistency.

When using abstract classes in a multithreaded scenario, each thread can inherit from the abstract class and implement its own behaviors in the abstract methods. Care must be taken to synchronize shared resources appropriately.

Here’s a simple example to illustrate how an abstract class can be used in a multithreaded environment:


        <?php
        abstract class Task {
            abstract protected function execute();
        }

        class MyTask extends Task {
            private $taskName;

            public function __construct($name) {
                $this->taskName = $name;
            }

            public function execute() {
                echo "Executing task: " . $this->taskName . "\n";
            }
        }

        class TaskThread extends Thread {
            private $task;

            public function __construct(Task $task) {
                $this->task = $task;
            }

            public function run() {
                $this->task->execute();
            }
        }

        $task1 = new MyTask("Task 1");
        $task2 = new MyTask("Task 2");

        $thread1 = new TaskThread($task1);
        $thread2 = new TaskThread($task2);

        $thread1->start();
        $thread2->start();

        $thread1->join();
        $thread2->join();
        ?>
