In this tutorial you will see the use of rewind method of FloatBuffer class..

Use of rewind() method in float buffer class.

In this tutorial, we will see the Use of rewind method of FloatBuffer class.

FloatBuffer API:

The java.nio.FloatBuffer class extends java.nio.Buffer class. It provides the following methods:

Return type	Method	Description
static FloatBuffer	allocate( int capacity)	The allocate(..)method allocate a new float buffer.
final boolean	hasRemaining()	The hasRemaining() method tell whether there are any elements in buffer or not.
final Buffer	rewind()	The rewind() method set the position zero and content not change.

   Code

import java.nio.*; import java.nio.FloatBuffer; public class FloatBufferRewind {   public static void main(String[] args) {     FloatBuffer floatBuf = FloatBuffer.allocate(55);     floatBuf.put(12.05f);     floatBuf.put(21.90f);     floatBuf.put(875.976f);     floatBuf.put(34.09f);     floatBuf.put(123.453f);     floatBuf.flip();   System.out.println("Contents in float buffer :");     while (floatBuf.hasRemaining()) {       System.out.print(floatBuf.get() + ",");     }     System.out.println("\n");     floatBuf.rewind();     System.out     .print("After using rewind method      content of float buffer : \n");     while (floatBuf.hasRemaining()) {       System.out.print(floatBuf.get() + ",");     }   } }

Output

C:\>java FloatBufferRewind Contents in float buffer : 12.05,21.9,875.976,34.09,123.453 After using rewind method content of float buffer : 12.05,21.9,875.976,34.09,123.453,
