Convert ByteBuffer to a FloatBuffer

import java.nio.ByteBuffer;
import java.nio.FloatBuffer;
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();
    FloatBuffer fb = ((ByteBuffer) bb.rewind()).asFloatBuffer();
    System.out.println("Float Buffer");
    while (fb.hasRemaining())
      System.out.println(fb.position() + " -> " + fb.get());
  }
}
/*
*/



Float Buffer
0 -> 0.0
1 -> 1.36E-43


Use while loop to read a FloatBuffer

import java.nio.ByteBuffer;
import java.nio.FloatBuffer;
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();
    FloatBuffer fb = ((ByteBuffer) bb.rewind()).asFloatBuffer();
    System.out.println("Float Buffer");
    while (fb.hasRemaining())
      System.out.println(fb.position() + " -> " + fb.get());
  }
}
/*

Float Buffer
