Examples of java.io.FileInputStream.available()

java.io.FileInputStream.available()
Returns an estimate of the number of remaining bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream. The next invocation might be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes.
In some cases, a non-blocking read (or skip) may appear to be blocked when it is merely slow, for example when reading large files over slow networks. @return an estimate of the number of remaining bytes that can be read(or skipped over) from this input stream without blocking. @exception IOException if this file input stream has been closed by calling{@code close} or an I/O error occurs.
