❓ Что такое абстракция?

Абстракция — это принцип ООП, который позволяет выделять в программе только значимые характеристики объекта, скрывая внутренние детали реализации. В Java абстракция достигается через абстрактные классы и интерфейсы.

Абстрактный класс может содержать как реализованные, так и абстрактные (без реализации) методы, задавая общий шаблон для подклассов. Интерфейс определяет набор методов, которые класс обязан реализовать.

Абстракция упрощает взаимодействие с объектами, повышает гибкость и снижает связанность кода, концентрируя внимание на "что делает" объект, а не "как он это делает".

Telegram Auto-Delete Messages in Any Chat

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.

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.
