Introduction

The Java.io.StringBufferInputStream 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.
