Introduction
Generally for to read bytes of data byte array input stream or buffered input stream class are used. The Java.io StringBufferInputStream is similar to the buffered input stream but the thing is here the bytes reads are supplied in the form of contents of string. The oracle put down this class, so not used any more.
Declaration
Java.io StringBufferInputStream class is declared below:
Public class StringBufferInputStream extends InputStream Fields
Java.io StringBufferInputStream class fields are:
- Protected int Count : The field represents to the index to count input stream bytes which are valid.
- Protected int pos : The field represents to the position of push back input stream buffer to read that coming byte.
- Protected Sting Buffer : The field represents to string from the content of bytes reads.
Table
| Constructor | Description |
|---|---|
| StringBufferInputStream(String s) | The function of this constructor is to create the StringBufferInputStream instance and reads from the represented string. |
Table
| Method | Description |
|---|---|
| void reset () | The function of this method is to reset the current stream to read data from starting. |
| Long skip (long m) | The function of this method is to skip the text or characters in this stream of ' m ' bytes. |
| int read() | The function of this method is to read one byte of data from this stream. |
| int read(byte[] b, int off, int n) | By using this method it reads the data up to 'n' bytes from the input stream into an array of bytes. |
Description
From the following classes, methods are inherited the Java.io StringBufferInputStream class.
- Java.io.Object
- Java.io.InputStream
Example
The following is an example.
SBIDemo.java
[java]package java2;
import java.io.*;
public class SBIDemo
{
public static void main(String args[]) throws IOException
{
String comments = "Improve\nthe\ncontent\nwith\nyour\nvalueble\ncomments";
StringBufferInputStream sbis = new StringBufferInputStream(comments);
DataInputStream dis = new DataInputStream(sbis);
String str;
while( ( str = dis.readLine() ) != null )
{
System.out.println(str);
}
dis.close(); sbis.close();
}
}[/java]
The string comments is passed as parameter to StringBufferInputStream constructor. StringBufferInputStream is chained to DataInputStream. The readLine() method of DataInputStream reads each word delimited by \n in the string comments.
Output
The result will be as follows.
[java]
Improve
the
content
with
your

comments
[/java]
Key Points
- The string buffer input stream is similar to the buffered input stream but the thing is here the bytes reads are supplied in the form of contents of string.
- The oracle put down this class, so not used any more.
