1. Concept Based on the memory, the data in the disk file is read into the memory in byte form. 2. Constructor public FileInputStream(File file) public FileInputStream(String pathname) Both of these create a byte input stream pipeline and connect it to the source file. Three. Methods public int read(): Returns one byte each time it […]

File byte input stream (FileInputStream) (basic stream, original stream)
IO streams are also called input and output streams. It is used to read and write data. I means I stands for input. The process of reading data from hard disk files tomemory is called input and is responsible for reading. O means O stands for output, which is the process of writing the data […]
Classification of IO streams in Java, byte stream and character stream, node stream and processing stream overview, FileInputStream, FileOutputStream, FireReader, FireWriter, BufferReader code
Classification of IO streams According to the different operation data units, it is divided into: byte stream and character stream According to the flow direction of the data flow, it is divided into: input flow and output flow According to the role of the flow, it is divided into: node flow and processing flow (packaging […]
Java node stream: FileInputStream\FileOutputStream
Article directory Byte input stream: InputStream Byte output stream: OutputStream FileInputStream FileOutputStream practise Byte input stream: InputStream The java.io.InputStream abstract class is the superclass of all classes that represent byte input streams, and can read byte information into memory. It defines basic generic functional methods for byte input streams. public int read(): Reads a byte […]
FileInputStream and FileOutputStream
Overview of FileInputStream and FileOutputStream FileInputStream and FileOutputStream are Java I/O A stream class for handling file input and output in . They are byte streams for reading and writing byte data. FileInputStream: used to read byte data from a file. It inherits from the InputStream class. By creating a FileInputStream object, you can open […]
FileInputStream and FileOutputStream
1. FileInputStream The FileInputStream class in Java is an input stream for reading files. It inherits from the InputStream class and can be used to read various types of files, including text files, binary files, audio and image files, etc. FileInputStream provides methods to read different parts of a file, such as bytes, characters, and […]
Java’s IO stream (1) — FileOutputStream+FileInputStream
1. Why learn IO flow? Since data cannot be permanently stored in memory, the data will be lost if the program stops. Therefore, it is necessary to save the data in a file on the hard disk. However, File can only operate on the file itself, not the content of the file, so IO stream […]
File, IO Stream, FileInputStream, FileOutputStream, FileReader and FileWriter are character streams
A file is where data is stored File stream: files are operated in the form of streams in the program java program (memory) file (disk) Stream: The path data takes between the data source (file) and the program (memory) Input stream: the path of data from the data source (file) to the program (memory) Output […]
