What is InputStream and OutputStream in Java?
The InputStream is used to read data from a source and the OutputStream is used for writing data to a destination. Here is a hierarchy of classes to deal with Input and Output streams. The two important streams are FileInputStream and FileOutputStream, which would be discussed in this tutorial.
Is InputStream an abstract class?
This abstract class is the superclass of all classes representing an input stream of bytes. Applications that need to define a subclass of InputStream must always provide a method that returns the next byte of input.
What are the direct subclasses of InputStream?
The InputStream subclasses are:
- ByteArrayInputStream.
- FileInputStream.
- PipedInputStream.
- BufferedInputStream.
- FilterInputStream.
- PushbackInputStream.
- DataInputStream.
- ObjectInputStream.
What are input and output streams explain them with illustrations?
Java defines two types of streams. They are, Byte Stream : It provides a convenient means for handling input and output of byte….Some important Byte stream classes.
| Stream class | Description |
|---|---|
| FileInputStream | Input stream that reads from a file |
| FileOutputStream | Output stream that write to a file. |
What is the difference between the two types of streams?
Java provides I/O Streams to read and write data where, a Stream represents an input source or an output destination which could be a file, i/o devise, other program etc. Byte Streams − These handle data in bytes (8 bits) i.e., the byte stream classes read/write data of 8 bits.
Which of the following is both input and output stream class?
iostream
Which stream class is used to both read and write on files?
fstream
What are different file stream classes?
A file stream can be defined using the classes ifstream, ofstream and fstream that contained in the header file fstream. The class to be used depends upon the purpose whether the write data or read data operation is to be performed on the file. A file can be opened in two ways: Using the constructor function of class.
What do input and output objects support?
4. What do input and output objects support? Explanation: cin and cout support null-terminated sequences as valid containers for sequences of characters.
