What is the ShortBuffer rewind() method in Java? Answer

java.nio.ShortBuffer is a class we can use to store a buffer of shorts. We can use this class’s rewind() method to rewind a buffer. Rewinding a buffer sets the buffer position to zero.

  • Limit of the buffer remains unaffected.
  • Any position previously marked is discarded.


The ShortBuffer.rewind() method is declared as follows:

  • buff: The ShortBuffer to rewind.

Return value

The ShortBuffer.rewind() method returns the ShortBuffer buff after rewinding.


Consider the code snippet below, which demonstrates the use of the ShortBuffer.rewind() method.

import java.nio.*;
import java.util.*;
public class main {
   public static void main(String[] args) {
      int n1 = 4;
      int n2 = 4;
      try {
         ShortBuffer buff1 = ShortBuffer.allocate(n1);

         System.out.println("buff1: " + Arrays.toString(buff1.array()));
         System.out.println("position at(before rewind): " + buff1.position());


         System.out.println("position at(after rewind): " + buff1.position());

         System.out.println("buff1: " + Arrays.toString(buff1.array()));
      } catch (IllegalArgumentException e) {
         System.out.println("Error!!! IllegalArgumentException");
      } catch (ReadOnlyBufferException e) {
         System.out.println("Error!!! ReadOnlyBufferException");


  • ShortBuffer buff1 is declared in line 8.
  • Two elements are added to buff1 using the put() method in lines 9-10. After adding the first element, the position of buff1 is incremented from 0 to 1. After adding the second element, the position of buff1 is incremented from 1 to 2.
  • The position of buff1 before rewind is 2. After calling the rewind() method in line 16, the position of buff1 is set to 0. This is why calling the put() method on buff1 adds the element at the 0th index of buff1.
