JavaInputStreamReaderis a bridge between byte streams and character streams. It reads bytes and decodes them into characters using a specified charset. It is recommended to wrap anInputStreamReaderwithin aBufferedReaderfor optimal efficiency. Note that when working with character streams in Java, we...
同时正因为它们实现了缓冲功能,所以要注意在使用BufferedOutputStream写完数据后,要调用flush()方法或close()方法,强行将缓冲区中的数据写出。否则可能无法写出数据。与之相似还BufferedReader和BufferedWriter两个类。 缓冲流相关类就是实现了缓冲功能的输入流/输出流。使用带缓冲的输入输出流,效率更高,速度更快。 字符...
In the above code, we create a BufferedReader object by passing an InputStreamReader initialized with the InputStream. We then use a while loop to read each line of the input stream usingreadLine()and append it to the StringBuilder. Finally, we close the reader and convert the StringBuilder...
Using the BufferedReader class However, the Scanner class is slow and may cause a "timelimit exceeded". We can read the input faster with the BufferedReader class. The class "MyScanner" below uses a BufferedReader. The same method names as in the Scanner class have been chosen, e.g. to...
In conclusion, converting anInputStreaminto aStream<String>in Java is made possible using techniques likeBufferedReaderwith itslines()method or leveraging theScannerwith itsfindAll()method. This allows for efficient processing of text-based data, providing flexibility and scalability when handling anInpu...
