私は、ProfileInputクラスを使用して、ダイアログボックスからJTextField入力を格納しています。それから私はそれをセッターメソッドとゲッターメソッドに移します。そこから私はAppFrameクラスのセッターメソッドとゲッタメソッドを呼び出しています。JTextField入力を表示するJLabelを取得できません
私が抱えている問題は、入力がGUI上のJLabelとして表示されないようにすることです。何も表示されません。私はコードを実行するときに表示されるエラーはありません。私が間違っていたものについての考え。
私はJavaを使い慣れていないため、学習しようとしています。何かを改善するためのアイデアや助けも素晴らしいです。

をご 'JLabel'は' fistNameInputTest'が '' STRING'ので、表示されないfirstNameTest 'は空です。あなたは 'AppFrame'クラスで' getFirstName() 'を呼び出しますが、初期化中に' ProfileInput'クラスの 'firstNameString'値が' null'だけである可能性があります。これを修正するには、新しいプロファイルが作成された後、おそらく 'firstNameInputTest'のテキストを更新する必要があります。 – MasterBlaster
