私は2つのクラスを持っています。1 つのクラスは gui 用で、もう 1 つのクラスはいくつかのスタッフを担当します。2 番目のクラスには Swingworker が含まれます。いくつかのログ ファイルを検索し、そこからいくつかの文を取得します。また、GUI には書き込みラベルがありSearching.. Please wait..、2 番目のクラスが作業を終了すると、に変更する必要がありますSearching is finished..。
このラベル名はsearchLabelファーストクラスで定義されています。プライベート変数です。
私の目的は次のとおりです。2番目のクラスにはdoneメソッドがあります。このメソッドの中で、やりたいことsearchLabel.setText("blabla");
これどうやってするの ？アクセスできません。また、パブリック JLabel を実行することは、私が考える解決策ではありません。この文字列を検索すると、コード内のその部分を簡単に見つけることができ/* PROBLEM IS IN HERE */ます。
ここにコードがあります
