Getting 2 blocks locations and saving them ?

Hi. How can I save 2 blocks locations? For example:

Code:java

 
public void onPlayerInteract(PlayerInteractEvent event) {
    Action action = event.getAction();
    Player player = event.getPlayer();
    Material defineItem = Material.matchMaterial(this.plugin.getConfig().getString("Define Block Item"));
    if(action == Action.RIGHT_CLICK_BLOCK) {
        int x1 = event.getClickedBlock().getX();
        int y1 = event.getClickedBlock().getY();
        int z1 = event.getClickedBlock().getZ();
        String world1 = event.getClickedBlock().getWorld().getName();
        if(player.getItemInHand().getType() == defineItem) {
            List<String> block1List = Arrays.asList("" + x1, "" + y1, "" + z1, "" + world1);
            //save block1List and then in another event I can use it
        }
    }
    if(action == Action.LEFT_CLICK_BLOCK) {
        int x2 = event.getClickedBlock().getX();
        int y2 = event.getClickedBlock().getY();
        int z2 = event.getClickedBlock().getZ();
        String world2 = event.getClickedBlock().getWorld().getName();
        if(player.getItemInHand().getType() == defineItem) {
            List<String> block2List = Arrays.asList("" + x2, "" + y2, "" + z2, "" + world2);
            //save block2List and then in another event I can use it
        }
    }
    if(action == Action.RIGHT_CLICK_BLOCK) {
        if(event.getClickedBlock() == block2List { //if the block that was clicked equals the block2List location
            player.teleport(block1List); //teleport them to block1List location
        }
        if(event.getClickedBlock() == block1List { //if the block that was clicked equals the block1List location
            player.teleport(block2List); //teleport them to block2List location
        }
    }
}
 

I need to be able to save the block1List and block2List and then when a player right clicks one of the blocks it teleports them to the other.

Thanks!

 

In your case, I would use a HashMap instead of a list. So you can map the locations to each other. And to make it easier to get the destination, you shouldn't convert the Location to a String, but save it in an instance of a class like Vector, as that is quite much easier to convert back to a Location afterwards. So you can use a HashMap<Vector,Vector> to store and to retrieve the locations. You can add each location pair twice, so the lookup works in both directions. If you want to permanently save the HashMap to a config, you will need to write your one de-/serialization code for it.
