Java BufferedInputStream reset() Example
BufferedInputStream class reset() method example. This example shows you how to use reset() method.
Syntax is : public void reset() throws IOException
This method resets the buffer to the specified marked position, If mark position is -1 (no mark has been set or the mark has been invalidated), an Exception is thrown. Otherwise, pos is set equal to mark position.
Here is the code.
/**
* @(#) ResetBufferedInputStream.java
* A class representing use of method reset() of BufferedInputStream class in
java.io Package.
* @Version 03-May-2008
* @author Rose India Team
*/
import java.io.*;
public class ResetBufferedInputStream {
public static void main(String[] args) throws IOException {
/* Construct an buffer input stream using some String value.
This is deprecated method in java api 1.6. */
StringBufferInputStream obj = new StringBufferInputStream("MAHENDRA");
// Construct the buffer using the buffer input stream obj.
BufferedInputStream bin = new BufferedInputStream(obj);
// read() method read elements one by one from the input stream buffer:
System.out.println("First element in buffer is : "+(char)bin.read());
// element at first position is marked.
bin.mark(0);
System.out.println("Next element in buffer is : "+(char)bin.read());
System.out.println("Next element in buffer is : "+(char)bin.read());
System.out.println("Next element in buffer is : "+(char)bin.read());
System.out.println("reset() method call so next element read will be "+
"first element .");
/* reset() method call.Method resets the buffer to the next element of
the marked element. */
bin.reset();
System.out.println("Next element in buffer is : "+(char)bin.read());
System.out.println("Next element in buffer is : "+(char)bin.read());
}
} |
Output of the program.
First element in buffer is : M
Next element in buffer is : A
Next element in buffer is : H
Next element in buffer is : E
reset() method call so next element read will be first element .
Next element in buffer is : A
Next element in buffer is : H |
