    double[] db1 = new double[] {};
    DoubleBuffer buffer1 = DoubleBuffer.wrap(db1);
    buffer1.put(db1);
    System.out.println(buffer1.remaining());
    double[] db2 = new double[] { 2325.54 };
    DoubleBuffer buffer2 = DoubleBuffer.wrap(db2);
    buffer2.put(db1);
    System.out.println(buffer2.remaining());
