Java Thread Pool and Runnable with For Loop: Potential Issue and Solution

The given code snippet creates a thread pool and executes a set of tasks using a for loop. Each task is represented by a Runnable object.\n\nHere's a breakdown of what the code does:\n\n1. The for loop iterates from 1 to 13.\n2. Inside the loop, a temporary variable 'temp' is declared and assigned the value of 'i'. However, this variable is not used in the code and can be removed.\n3. A new Runnable object 'r' is created using an anonymous inner class. This object represents the task to be executed by a thread in the thread pool.\n4. The run() method of the Runnable object is implemented to print the current thread's name and the value of 'i'.\n5. The Runnable object 'r' is submitted to the thread pool 'pool' using the execute() method.\n6. The loop continues until all tasks have been submitted to the thread pool.\n\nNote: The issue with this code is that the value of 'i' is accessed from within the anonymous inner class, which is executed by multiple threads. Since the loop completes before the tasks start running, the value of 'i' will be shared among all threads and may not have the expected output. To fix this, the value of 'i' should be effectively final or a separate variable should be created within the loop to be used in the inner class.
