Convert ByteBuffer to DoubleBuffer

   <source lang="java">

import java.nio.ByteBuffer; import java.nio.DoubleBuffer; public class MainClass {

 public static void main(String[] args) {
   ByteBuffer bb = ByteBuffer.wrap(new byte[] { 0, 0, 0, 0, 0, 0, 0, "a" });
   bb.rewind();
   DoubleBuffer db = ((ByteBuffer) bb.rewind()).asDoubleBuffer();
   System.out.println("Double Buffer");
   while (db.hasRemaining())
     System.out.println(db.position() + " -> " + db.get());
 }

} /*

Create a DoubleBuffer

   <source lang="java">

import java.nio.ByteBuffer; import java.nio.DoubleBuffer; public class Main {

 public static void main(String[] argv) throws Exception {
   ByteBuffer buf = ByteBuffer.allocate(15);
   DoubleBuffer dbuf = buf.asDoubleBuffer();
 }

}</source>

Use While loop to read a DoubleBuffer

   <source lang="java">

import java.nio.ByteBuffer; import java.nio.DoubleBuffer; public class MainClass {

 public static void main(String[] args) {
   ByteBuffer bb = ByteBuffer.wrap(new byte[] { 0, 0, 0, 0, 0, 0, 0, "a" });
   bb.rewind();
   DoubleBuffer db = ((ByteBuffer) bb.rewind()).asDoubleBuffer();
   System.out.println("Double Buffer");
   while (db.hasRemaining())
     System.out.println(db.position() + " -> " + db.get());
 }

} /*
