Question: What is DataInputStream and DataOutputStream in Java?

The DataInputStream class read primitive Java data types from an underlying input stream in a machine-independent way. While the DataOutputStream class write primitive Java data types to an output stream in a portable way.

What is DataOutputStream in Java?

DataOutputStream in Java is a filter output stream that provides methods for writing Javas standard data types. It enables you conveniently to write strings and all primitive data types such as boolean, int, float, long, etc to a stream.

What is the purpose of Java DataInputStream and OutputStream?

Java DataOutputStream class allows an application to write primitive Java data types to the output stream in a machine-independent way. Java application generally uses the data output stream to write data that can later be read by a data input stream.

What is FileInputStream and FileOutputStream in Java?

In Java, FileInputStream and FileOutputStream are byte streams that read and write data in binary format, exactly 8-bit bytes. They are descended from the abstract classes InputStream and OutputStream which are the super types of all byte streams.

Why do we use Dataoutputstream?

A data output stream lets an application write primitive Java data types to an output stream in a portable way. An application can then use a data input stream to read the data back in.

What is the use of FileInputStream?

Java FileInputStream class obtains input bytes from a file. It is used for reading byte-oriented data (streams of raw bytes) such as image data, audio, video etc. You can also read character-stream data. But, for reading streams of characters, it is recommended to use FileReader class.

What is difference between FileReader and FileInputStream?

So starting of with FileReader class in java is used to read data from the file. It returns data in byte format like FileInputStream class....Java.FileInputStreamFileReaderFileInputStream is used for reading binary files.FileReader is used for reading text files in platform default encoding.6 more rows•Jun 23, 2021

What is difference between FileInputStream and FileReader in java?

FileInputStream is Byte Based, it can be used to read bytes. FileReader is Character Based, it can be used to read characters. FileInputStream is used for reading binary files. FileReader is not used for Serialization and DeSerialization, as it reads characters not bytes.

What is RandomAccessFile in java?

RandomAccessFile(File file, String mode) Creates a random access file stream to read from, and optionally to write to, the file specified by the File argument. RandomAccessFile(String name, String mode) Creates a random access file stream to read from, and optionally to write to, a file with the specified name.
