What code can i send message all player only in my party ?

I've created a party plugin, But I can't make a code to send message to all player on my party.

I'm sorry, I'm not good in english and coding.

String message = ...;
Player sender = ...;
for (Player player : Bukkit.getOnlinePlayers()) {
    if (Parties.areInSameParty(sender, player) {
         player.sendMessage(message);
    }
}

String message = ...;
Player sender = ...;
for (Player player : Bukkit.getOnlinePlayers()) {
    if (Parties.areInSameParty(sender, player) {
         player.sendMessage(message);
    }
}

This is one of the least optimised methods you could possibly do. For scaling-up performance, you want to know how to write efficient code. Let's put this into a larger perspective: Imagine the code base is for thousands of players at a single time - your code would hold up the server to an extent. I know this is only sending a message, but you would be doing constant checks for every player online, whenever you wanted to send a party message.

As previously mentioned, it would be ideal to have a party object which handles everything. Takes for instance:

public final class Party {
  
    public static Builder builder()
    {
        return new Builder();
    }
  
    public static final class Builder implements org.apache.commons.lang3.builder.Builder<Party>
    {
      
        private UUID owner;
        private Set<UUID> members;
      
        Builder()
        {
          
        }
      
        @Override
        public Party build()
        {
            Objects.requireNonNull(this.owner, "owner");
          
            return new Party(this.owner, this.members == null ? new HashSet<>() : this.members);
        }
      
        public Builder setOwner(UUID owner)
        {
            this.owner = owner;
            return this;
        }
      
        public Builder setMembers(Collection<UUID> members)
        {
            Objects.requireNonNull(members, "members");
          
            this.members = new HashSet<>(members);
            return this;
        }
      
        public Builder addMember(UUID uniqueId)
        {
            Objects.requireNonNull(uniqueId, "uniqueId");
          
            this.members.add(uniqueId);
            return this;
        }
      
    }
  
    private UUID owner;
    private final Set<UUID> members = ConcurrentHashMap.newKeySet();
  
    Party(UUID owner, Set<UUID> members)
    {
        this.owner = owner;
        this.members.addAll(members);
    }
  
    public UUID getOwner()
    {
        return this.owner;
    }
  
    public Set<UUID> getMembers()
    {
        return Collections.unmodifiableSet(this.members);
    }
  
    public void addMember(UUID uniqueId)
    {
        this.members.add(uniqueId);
    }
  
    public void removeMember(UUID uniqueId)
    {
        this.members.remove(uniqueId);
    }
  
    public boolean isMember(UUID uniqueId)
    {
        return this.members.contains(uniqueId);
    }
  
    public void sendPartyMessage(String message)
    {
        this.members.stream()
                .map(Bukkit::getPlayer)
                .filter(Objects::nonNull)
                .forEach(player -> player.sendMessage(message));
    }
  
}

The code above would be a more preferred example. You could go a step further and cache which players are online in the party. I am sure you can work how to do that out.
