### Question:
BigIntegerAccessor implements PropertyAccessor<BigInteger> { public BigInteger getInstance(Class<?> clazz) { return BigInteger.TEN; }  @Override BigInteger fromBytes(Class targetClass, byte[] b); @Override byte[] toBytes(Object object); @Override String toString(Object object); @Override BigInteger fromString(Class targetClass, String s); @Override BigInteger getCopy(Object object); BigInteger getInstance(Class<?> clazz);  }### Answer:
@Test public void testGetInstance() { Assert.assertEquals(BigInteger.TEN, accessor.getInstance(BigInteger.class)); }
