Curious how is it possible that An interface can be instantiated(line 10 - line 20) ?

So, the ATable is actually an Interface. If I remembered correctly, neither Interface nor abstract class can be instanciated, i.e you cannot do like : InterfaceName instance = new InterfaceName(){}; However, at round line 10-20, we do have an instance of an interfac :

ATable aTable = new ATable() {
    @Override
    public String getCurrentUserName() {
        return "Amigo";
    }

    @Override
    public String getTableName() {
        return "DashboardTable";
    }
};

How is it be possible ??
