Should I capitalize my constants?

const int MY_CONSTANT = 5;

const int myConstant = 5;

SomeConstant

public static final String  ID_FOO_BAR = "org.acme.foo.bar";
public static final List<String> sList = new List<String>();
public static final List<String> LIST = Collections.unmodifiableList(sList);
public static final String[] sArray = new String[] {"foo", "bar", "baz" }; // FindBugs complains, if this is public.
public static final List<String> ARRAY = Arrays.asList(sArray);

THIS_CONSTANT

const size_t size = v.size();
for( size_t i = 0; i < size; ++i ) ...
