    Hello, I want to make, when you throw identified snowball (named), then it explodes, any helps?

    Code:
        @EventHandler
    public void onProjectileHit(ProjectileHitEvent event) {
        Projectile projectile = event.getEntity();
        Player p = (Player) event.getEntity().getShooter();
        if (projectile instanceof Snowball) {
            Snowball snowball = (Snowball) projectile;
            String name = p.getItemInHand().getType().name();
            if(name.equals("hi")){
            snowball.getWorld().createExplosion(snowball.getLocation(), 3F);
            }
        }
    }

    You need to set the displayName of the entity snowball, then get back later in the projectile hit event

    Not in-game.
    Create a projectileLaunch event, and if the snowball's name is for example hi, then rename the spawned snowball to hi.
    Entity#setDisplayName(String s)
    In the projectileHitEvent, get the entity's name (Entity#getDisplayName()), and if it is equal to hi, then create the explosion

    Why are you doing this?

    Code:
     String name = p.getItemInHand().getType().name();
    Also can you show us the error please? or what line is not working?

    What is on line 39 of your code? Also I would recommend getting the ItemMeta and getting the displayName() instead of what you are doing

    It doesn't have a custom name then.
    Instead of doing getType().name() (this returns SNOWBALL), do getItemMeta().getDisplayname()
