The 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.

Class declaration

Following is the declaration for class:

public abstract class InputStream
   extends Object
      implements Closeable

Single Constructor

Class methods

S.N.Method & Description
1 int available()
This method eturns 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 void close()
This method closes this input stream and releases any system resources associated with the stream.
3 void mark(int readlimit)
This method marks the current position in this input stream.
4 boolean markSupported()
This method tests if this input stream supports the mark and reset methods.
5 abstract int read()
This method reads the next byte of data from the input stream.
6 int read(byte[] b)
This method reads some number of bytes from the input stream and stores them into the buffer array b.
7 int read(byte[] b, int off, int len)
This method reads up to len bytes of data from the input stream into an array of bytes.
8 void reset()
This method repositions this stream to the position at the time the mark method was last called on this input stream.
9 long skip(long n)
This method skips over and discards n bytes of data from this input stream..
