Java Foreach Loop with Timer for Delayed Iteration

Here is an example of how you can use a 'foreach' loop and a Timer to implement a delay of 1 second every 10 iterations:

import java.util.List;
import java.util.Timer;
import java.util.TimerTask;

List<InstList> instLists = instListMapper.selectInstListList(list);
int size = instLists.size();

// Define the number of iterations before the delay
int iterationsBeforeDelay = 10;

for (int i = 0; i < size; i++) {
    // Perform the desired actions for each iteration

    // Check if it's time for a delay
    if ((i + 1) % iterationsBeforeDelay == 0) {
        // Create a Timer object
        Timer timer = new Timer();

        // Schedule a TimerTask to be executed after 1 second
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                // Actions to be performed after the delay
            }
        }, 1000); // 1000 milliseconds = 1 second

        // Wait for the TimerTask to complete
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        // Cancel the timer
        timer.cancel();
    }
}

In this example, the 'instLists' list contains 119 elements. The loop iterates through each element, and after every 10 iterations, it creates a Timer object to introduce a delay of 1 second. After the delay, you can perform any desired actions.
