### Question:
FloatAccessor implements PropertyAccessor<Float> { @Override public Float fromBytes(Class targetClass, byte[] data) { if (data == null || data.length != 4) return (float) 0x0; return Float.intBitsToFloat(toInt(data)); }  @Override Float fromBytes(Class targetClass, byte[] data); @Override byte[] toBytes(Object object); @Override String toString(Object object); @Override Float fromString(Class targetClass, String s); @Override Float getCopy(Object object); Float getInstance(Class<?> clazz);  }### Answer:
@Test public void testFromBytes() { Assert.assertEquals(0.0f, accessor.fromBytes(Float.class, null)); Float f1 = new Float(4.555); byte[] b = accessor.toBytes(f1); Float f2 = accessor.fromBytes(Float.class, b); Assert.assertEquals(f1, f2); }
