Bukkit event thrown on creeper destruction or enderman block-taking?

Question

What is the name of the event that gets triggered when a creeper destroys blocks, and how do I use it?

Similarly, when an Enderman steals a block from the world, another event is called, what is it and how is it used?

Answer 1

When a Creeper destroys blocks via explosion, the event EntityExplodeEvent is called. You can check an example on how to use it below:

@EventHandler
public void onCreeperExplode(EntityExplodeEvent e) {
    Entity entity = e.getEntity();
    if (entity.getType().equals(EntityType.CREEPER)) {
    //It's a creeper
    //You can cancel it
    e.setCancelled(true);    //This prevents damage

    //Or cancel the block destruction
    e.blockList().clear();
    }
}

For the Enderman block-taking, you can use an EntityBlockChangeEvent, called whenever an entity changes a block (excluding players).

@EventHandler
public void onEndermanBlockTake(EntityChangeBlockEvent e) {
    Entity entity = e.getEntity();
    if (entity.getType().equals(EntityType.Enderman)) {
        //It's an enderman
        Block b = e.getBlock();    //Getting the block
        e.setCancelled(true);    //Cancelling the event
    }
}
