I’m curious if there are things in the standard class library that you find useful but not widely used.

      Link for the curious

      A PushbackInputStream adds functionality to another input stream, namely the ability to “push back” or “unread” bytes, by storing pushed-back bytes in an internal buffer. This is useful in situations where it is convenient for a fragment of code to read an indefinite number of data bytes that are delimited by a particular byte value; after reading the terminating byte, the code fragment can “unread” it, so that the next read operation on the input stream will reread the byte that was pushed back. For example, bytes representing the characters constituting an identifier might be terminated by a byte representing an operator character; a method whose job is to read just an identifier can read until it sees the operator and then push the operator back to be re-read.

      This does sound useful. I have to admit I don’t know much about InputStream and OutputStream and every time I need to do something with them (which is rare) I just search it up.
