In my journey with Java, I found the I/O system fascinating and essential for handling data effectively. Here’s a quick rundown:
Java I/O categories: - Byte streams: Handle raw binary data (e.g., images, audio). - Character streams: Deal with text data, making it human-readable.
Key Classes: - InputStream and OutputStream for byte streams. - Reader and Writer for character streams.
Common Operations: 1. Reading data:
FileInputStream fis = new FileInputStream("file.txt"); int data = fis.read();
2. Writing data:
FileOutputStream fos = new FileOutputStream("file.txt"); fos.write(data);
Important Tips: - Always close streams using try-with-resources to prevent memory leaks. - Use buffering classes (like BufferedInputStream) for efficient data handling.

China’s stock markets are some of the largest in the world, with total market capitalization reaching RMB 79 trillion (US$12.2 trillion) in 2020. China’s stock markets are seen as a crucial tool for driving economic growth, in particular for financing the country’s rapidly growing high-tech sectors.Although traditionally closed off to overseas investors, China’s financial markets have gradually been loosening restrictions over the past couple of decades. At the same time, reforms have sought to make it easier for Chinese companies to list on onshore stock exchanges, and new programs have been launched in attempts to lure some of China’s most coveted overseas-listed companies back to the country.
