The Java.io.InputStream 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.
Following is the declaration for Java.io.InputStream class −
public abstract class InputStream extends Object implements Closeable
|Sr.No.||Constructor & Description|
|Sr.No.||Method & Description|
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.
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.
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.
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.
This class inherits methods from the following classes −
