What are the read and write operations of Java IO stream creation?
Article Introduction:The concept of IO stream can be initially understood as the transmission of data. We put a set of data into: 1234567 and transfer them from the hello file to the haha file. If you use the program method to transfer, you need to transfer them one by one. That is to say, it is a byte-by-byte transmission. We can only pass in or read one byte at a time. This is the general process of the io stream. The io stream can read any type of file. Such as: text files, pictures, songs mp3, videos, etc. Because the io stream is read byte by byte, we need to use the byte single-byte variable to get the length. If you get too much content, you need to use the corresponding array. The method corresponding to the io stream needs to be written in all io stream methods.

Is there a concept of reading the output of a program as a stream line by line?
Article Introduction:I have a shell command (e.g. journalctl -f-ojson) that continuously streams lines to standard output. I want to retrieve this output line by line and process it further. The documentation for os/exec addresses how to read the output of the command and handle the io stream buffer. It seems to me that processing all goes through a fixed buffer which is read in, processed and further written to. My problem is that the size of this buffer is fixed and independent of the content. Is there a way to read the incoming stream (in my case the output of the shell command) line by line? Maybe there is a higher level library than io reader?
