Jun 20, 2017 · In this case, the best approach is to write using a DataOutputStream wrapping a BufferedOutputStream, setting the buffer size to some number (e.g. 64k) to maximize I/O throughput. The keys are increasing but with possible large gaps. In this case using an OutputStream would require zeros to be written in the gaps in the file.

Feb 6, 2025 · A file that is read or written using a sequential stream is called a sequential-access file. The data of a sequential-access file cannot be updated. So, for reading and writing data simultaneously, Java provides the RandomAccessFile class.

With a sequential access file, on average you'd have to read half the zip file before finding the file that you wanted. With a random access file, you only read the directory and the file that you need. The RandomAccessFile class in the java.io package implements a random access file.

An example of creating and writing to a sequential file using java, as well as reading from the file to display its contents. The code demonstrates the use of the createsequentialfile and readsequentialfile classes, which allow for the creation, writing, and reading of …

FileChannel implements SeekableByteChannel allowing you to manage random access files using channels. Methods size, position, truncate allow you to read and write files randomly. see http://www.zoftino.com/java-random-access-files for details and example.

We first demonstrate sequential-access files using text files, allowing the reader to quickly create and edit human-readable files. In the subsections of this chapter we discuss creating, writing data to, reading data from and updating sequential-access text files.
