キーワードを削除する必要があると言われたstaticので、削除すると、この1つのエラーが発生しました。コードの操作を手伝ってもらえますか?私はOOPを練習していて、これらの静的修飾子についてもっと知りたいです。どうもありがとうございます!

使用staticすると、ここで使用している暗黙のオブジェクトがないと言っています。ただしTerm、静的として定義していません。オブジェクトで b する必要があると言っています。

あなたの場合、最も簡単なことは、static非静的である必要がないように見えるので、Term を作成することです。

static class Term {
    String num;          
    boolean used;
}

一般に、ネストされたクラスは可能な限り静的にします。一部はパフォーマンスのためですが、ほとんどは明確にするためです。

キーワード static を削除する必要があります

の宣言でキーワードを削除してはなりませstaticserialVersionUID

コードのどの行でコンパイル エラーが発生するかはわかりませんが、明らかにその周りの何かも静的である必要があります。

やみくもにアドバイスに従うだけではいけません。それが何を意味するのか、そしてそれがあなたが行ったことすべてに本当に当てはまるかどうかを常に尋ねてください。このビジネスには、カットアンドペースト、暗記プログラミング、カーゴカルト プログラミングがたくさんあります。それがどこから来ようとも、それに加担しないでください。悲しいことに、そのかなりの割合は同僚や上司からのものです。それに対処する方法を学ばなければなりません。

用語は内部クラスなので、以下のように内部クラスのインスタンスを作成します

Term term = qWindow.new Term();
