When will you get ‘ReadOnlyBufferException’?

'ReadOnlyBufferException' thrown, when you try to insert data into a read only buffer.

package com.sample.nio;

import java.nio.ByteBuffer;

public class Test {

 public static void main(String args[]) throws Exception {
  /* Define new byte buffer of capacity 11 */
  ByteBuffer byteBuffer = ByteBuffer.allocate(26);

  /* Get the read-only buffer from byteBuffer */
  ByteBuffer readOnlyBuffer = byteBuffer.asReadOnlyBuffer();

  readOnlyBuffer.put(5, (byte) 67);

 }
}

When you ran able application, you will endup in 'ReadOnlyBufferException'.
