Javaでテトリスの実装をさせているのですが機能として次にくるブロックを表示させる機能追加をしようとしていて別途でnextblockpaenlを作成したのですが(コード2)、コード1の中にどのようにして組み込めばいいのか分かりません。
どうすれば動くようになるのでしょうか?

このコードはあなたが作ったものではないようですね。
元コードを理解していれば、このような全く違う描画ロジックを採用するはずがないからです。
とりあえず、やっつけで座標調整等はしてないですが、次ブロック表示機能を入れてみましたので、載せておきます。
作ったパネルはmain()のところでadd()しています。これを踏まえて、スタートボタンや点数表示などを追加してみてはいかがですか?
