javaで作成したインターフェイスでインスタンスのデータ型プロパティの値を削除しようとしていますが、動作しません。それは私に与えますJenaでデータ型のプロパティの値を削除できません
Exception in thread "AWT-EventQueue-0" java.util.ConcurrentModificationException.
なぜ私は理解できません。何が間違っているのか教えていただけますか？ここで
は、ボタン削除のために私のコードです：
//Button Remove
public class ActionRemove implements ActionListener
{
public void actionPerformed(ActionEvent evt)
{
StmtIterator iter = onto.model.listStatements();
while (iter.hasNext())
{
Statement stmt = iter.nextStatement();
Resource subject = stmt.getSubject();
Property predicate = stmt.getPredicate();
RDFNode object = stmt.getObject();
if(subject.toString().equals (onto.uriBase+"#"+tabTF[0].getText()))
{
onto.model.remove(stmt);
}
}
}
}
