Вопрос с собеседования

Какими характеристиками должен обладать метод, чтобы функциональный интерфейс был функциональным?

Ответ: 1. Единственный абстрактный метод (SAM - Single Abstract Method) – в интерфейсе должен быть ровно один абстрактный метод.
2. Допустимые default и static методы – могут присутствовать, но не считаются абстрактными.
3. Совместимость с лямбда-выражениями – позволяет использовать функциональный стиль.

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
