Best way to run a method many times after certain amount of time?

Hello Bukkit,

For a plugin I'm developing, I need to edit a block, and after 1 minute need to restore the block back to its original material. Is it bad practice to make a delayed task runnable for each of the blocks? There is the possibility of hundreds of these delayed tasks. If so, is there a better way to go about this?

Cheers,

If you are looking to use the same runnable multiple times at once:

PHP:

for (int i = 100; 1 > 0; i--) {
  // Insert code here
}

The way I would do this is (depending on how frequently you NEED to check) register a runnable to repeat every second, loop through a hashmap which contains info of the block and the time it was placed, then replace them if the time is equal to 1 minute. I'm not sure if there's a more efficient way though, no.
