に失敗スプリット（）メソッドは、私は次の形式のテキストファイルを読んでいる
try {
String path="contenidoDelMuseo.txt";
File myFile = new File (path);
FileReader fileReader = new FileReader(myFile);
BufferedReader reader = new BufferedReader(fileReader);
String line = null;
while ((line=reader.readLine())!=null){
String [] fields = line.split("\\*");
}
アンはIndexOutOfBoundsExceptionが、私はfields[1]にアクセスしようとするたびにスローされます。どうして？
編集：クラスのコード全体は、私はあなたのデータを使用してコードを実行した
