Java.io.InputStream Class
Introduction
The Java.io.InputStream class is the superclass of all classes representing an input stream of bytes. Apppcations that need to define a subclass of InputStream must always provide a method that returns the next byte of input.
Class declaration
Following is the declaration for Java.io.InputStream class −
pubpc abstract class InputStream extends Object implements Closeable
Class constructors
Sr.No. | Constructor & Description |
---|---|
1 | InputStream() Single Constructor |
Class methods
Sr.No. | Method & Description |
---|---|
1 | This method returns an estimate of the number of 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. |
2 | This method closes this input stream and releases any system resources associated with the stream. |
3 | This method marks the current position in this input stream. |
4 | This method tests if this input stream supports the mark and reset methods. |
5 | This method reads the next byte of data from the input stream. |
6 | This method reads some number of bytes from the input stream and stores them into the buffer array b. |
7 | This method reads up to len bytes of data from the input stream into an array of bytes. |
8 | This method repositions this stream to the position at the time the mark method was last called on this input stream. |
9 | This method skips over and discards n bytes of data from this input stream. |
Methods inherited
This class inherits methods from the following classes −
Java.io.Object
