String.format() is Capitalizing Arguments

Question

I have a String format String:

String.format("CREATE TABLE %s ("
    + "%S INTEGER PRIMARY KEY AUTOINCREMENT, %s INTEGER NOT NULL, %s TEXT NOT NULL)",
    SPORT_TABLE, SPORT_ID, SPORT_WSID, SPORT_TITLE);

But my second argument (SPORT_ID) is being capitalized. Why is this happening? What can I do to fix this?

Answer 1

It is a perfectly documented behavior even if not a well known one (probably because it's neither an obvious need nor something very useful).

From the javadoc :

The following table summarizes the supported conversions. Conversions denoted by an upper-case character (i.e. 'B', 'H', 'S', 'C', 'X', 'E', 'G', 'A', and 'T') are the same as those for the corresponding lower-case conversion characters except that the result is converted to upper case according to the rules of the prevailing Locale. The result is equivalent to the following invocation of String.toUpperCase()
