public class BufferToArray {
public static void main(String[] args) {
   try {
FloatBuffer floatBuf1 = FloatBuffer.allocate(1024);
      floatBuf1.put(12.98f);
      floatBuf1.put(54.4f);
      floatBuf1.put(78.94f);
      floatBuf1.put(87.56f);
      float[] s = new float[4];
      floatBuf1.flip();
      floatBuf1.get(s);
  System.out.println("Content of a float array.");
      for (int i = 0; i < s.length; i++) {
