public class onJoin implements Listener {
	
	Location locationRaw;
	Location locationRaw2;
	Location location;
	Location location2;
	
	@EventHandler
	private void onPlayerJoin(PlayerJoinEvent e) {
		for(Player p : Bukkit.getOnlinePlayers()) {
			
			World world = Bukkit.getWorlds().get(0);
			int X = getRandom(1500, -1500);
			int Y = getRandom(250, 1);
			Block blockY = world.getBlockAt(location2);
			if(blockY.getType() == Material.GRASS_BLOCK) {
				int rawY = world.getHighestBlockYAt(locationRaw2);
				int Z = getRandom(1500, -1500);
	
				locationRaw2 = new Location(world, X, Y, Z);
				locationRaw = new Location(world, X, rawY, Z);
				location = new Location(world, X, rawY -2, Z);
				location2 = new Location(world, X, rawY -1, Z);
				
				Block block1 = world.getBlockAt(locationRaw);
				block1.setType(Material.AIR);
				Block block2 = world.getBlockAt(locationRaw);
				block2.setType(Material.AIR);
				Block block3 = world.getBlockAt(location2);
				block3.setType(Material.AIR);
				
				p.setBedSpawnLocation(location);
				p.teleport(location);
			}
		}
	}
	
	public int getRandom(int lower, int upper) {
	    Random random = new Random();
	    return random.nextInt((upper - lower) + 1) + lower;
	}
