The class allows an application to create an input stream in which the bytes read are supplied by the contents of a string. Applications can also read bytes from a byte array by using a ByteArrayInputStream.Only the low eight bits of each character in the string are used by this class.

This class has been deprecated by Oracle and should not be used any more.

Class declaration

Following is the declaration for class −

Class methods

Sr.No. Method & Description

int available()

This method returns the number of bytes that can be read from the input stream without blocking.


int read()

This method reads up to len bytes of data from this input stream into an array of bytes.


void reset()

This method resets the input stream to begin reading from the first character of this input stream's underlying buffer.
