❓ Что такое autoboxing?

Autoboxing — это автоматическое преобразование примитивных типов в соответствующие им классы-обёртки. Например, преобразование int в Integer, double в Double и так далее. Это упрощает работу с коллекциями, поскольку они могут хранить только объекты, а не примитивы. Autoboxing происходит автоматически, когда примитив передаётся в место, где требуется объект.

Примечание: Также существует обратный процесс — unboxing, когда объект обёртки автоматически преобразуется в примитивный тип.

NEWS: Telegram supports Facetime video calls NOW!

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.

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.
