Convert ByteBuffer to a LongBuffer

   <source lang="java">

import java.nio.ByteBuffer; import java.nio.LongBuffer; 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();
   LongBuffer lb = ((ByteBuffer) bb.rewind()).asLongBuffer();
   System.out.println("Long Buffer");
   while (lb.hasRemaining())
     System.out.println(lb.position() + " -> " + lb.get());
 }

} /*

Create a long ByteBuffer

   <source lang="java">

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

 public static void main(String[] argv) throws Exception {
   ByteBuffer buf = ByteBuffer.allocate(15);
   LongBuffer lbuf = buf.asLongBuffer();
 }

}</source>

Loop through a LongBuffer with a while loop

   <source lang="java">

import java.nio.ByteBuffer; import java.nio.LongBuffer; 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();
   LongBuffer lb = ((ByteBuffer) bb.rewind()).asLongBuffer();
   System.out.println("Long Buffer");
   while (lb.hasRemaining())
     System.out.println(lb.position() + " -> " + lb.get());
 }

} /*
