❓ В чём разница между методами submit() и execute() в ExecutorService?

И submit(), и execute() используются для запуска задач в пуле потоков, но между ними есть важные отличия:

— execute(Runnable) запускает переданную задачу асинхронно, но не возвращает никакого результата. Если во время выполнения возникнет исключение, оно не передаётся явно обратно.

— submit(Runnable/Callable) также запускает задачу асинхронно, но возвращает объект типа Future. С помощью этого объекта можно получить результат задачи (future.get()), проверить статус её выполнения (future.isDone()), явно обработать исключение, если оно произошло во время выполнения задачи.

The SSE was the first modern stock exchange to open in China, with trading commencing in 1990. It has now grown to become the largest stock exchange in Asia and the third-largest in the world by market capitalization, which stood at RMB 50.6 trillion (US$7.8 trillion) as of September 2021.

The Main Board mainly hosts large, well-established Chinese companies and lists both A-shares and B-shares.

How Does Bitcoin Work?

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
