Строковое представление экземпляра. По умолчанию возвращает "ПолноеИмяКласса@хэшВ16тиричномВиде" (например "java.lang.Object@1a23b4f"). Часть после @ – не адрес в памяти, так что умолчательная реализация почти не несет практической пользы. Полезно добавлять нормальную реализацию даже если не необходимо в логике программы – поможет в отладке. Готовый вызов x.toString() с проверкой на null уже реализован в String.valueOf(x).

Multiple pro-Kremlin media figures circulated the post's false claims, including prominent Russian journalist Vladimir Soloviev and the state-controlled Russian outlet RT, according to the DFR Lab's report. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. Founder Pavel Durov says tech is meant to set you free But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. The S&P 500 fell 1.3% to 4,204.36, and the Dow Jones Industrial Average was down 0.7% to 32,943.33. The Dow posted a fifth straight weekly loss — its longest losing streak since 2019. The Nasdaq Composite tumbled 2.2% to 12,843.81.
