私はEclipseを使用してプログラムをビルドしています。実行すると「エラーがあります」と表示されますが、とにかく実行します。コンソールにエラーが表示されず、アプリケーションで空の画面が表示されます。どうしてこれなの？Eclipseに「エラーはありますがコンソールには何も表示されません」と表示されるのはなぜですか？
追加情報：私は最近、非常に粗雑なフォームからGridBagLayoutを使用するように、以前のレイアウトを変更しようとしていましたが、私はレイアウトの使用に慣れていません。変更を試みる前に、プログラムが適切に機能して以来、私のレイアウトに問題がある、あるいはその周りを回っていることを強く疑う。ここで
レイアウトを必要とする私の2つの主なクラスがあり、それは厄介なことのために申し訳ありませんが、私はそれに戻って復帰しなければならない場合には、以前のレイアウトのために働いていたラインの多くをコメントアウト：

Eclipseエラーを表示するには、「エラーログ」ビューを開きます。 「問題」ビューを開いて、コードやビルドプロセスの問題を確認します。 –
