Using configured settings within your plugin

Our current EventHandler of the MobEnhancer plugin sets the health of zombies to 40. The number 40 is hardcoded. This means that the value of 40 is a part of the code itself, and cannot be changed after the code is compiled. We wish to make this value softcoded which, as you can guess, is retrieving the value from an external source, in our case, config.yml.

Currently our onMobSpawn method is as follows:

@EventHandler
public void onMobSpawn(CreatureSpawnEvent event) {
    if (event.getEntityType() == EntityType.ZOMBIE) {
        int health = 40;
        event.getEntity().setMaxHealth(health);
        event.getEntity().setHealth(health);
    }
}

We will work from this existing code. The if statement is no longer needed, because we don't want to limit the plugin to only zombies. As we discussed earlier, we also want to remove the hardcoded 40 with an integer that will be read from the config file. Therefore, 40 should be replaced with getConfig(...
