com.sun.util.PrintfFormat

ConversionSpecification allows the formatting of a single primitive or object embedded within a string. The formatting is controlled by a format string. Only one Java primitive or object can be formatted at a time.

A format string is a Java string that contains a control string. The control string starts at the first percent sign (%) in the string, provided that this percent sign

is not escaped protected by a matching % or is not an escape % character,
is not at the end of the format string, and
precedes a sequence of characters that parses as a valid control string.

A control string takes the form:

 % ['-+ #0]* [0..9]* { . [0..9]* }+ { [hlL] }+ [idfgGoxXeEcs]

The behavior is like printf. One (hopefully the only) exception is that the minimum number of exponent digits is 3 instead of 2 for e and E formats when the optional L is used before the e, E, g, or G conversion character. The optional L does not imply conversion to a long long double.

    private static List<StringIdEntity> createTestEntitiesString(int count) {
        List<StringIdEntity> entities = new ArrayList<StringIdEntity>();


        for (int i = 1; i <= count; i++) {
            String id = "entity" + i;
            String milliseconds = new PrintfFormat("%03d").sprintf(i);
            Date timestamp = DateUtils.createDate("2011-06-01T14:00:00." + milliseconds);
            StringIdEntity testEntity = new StringIdEntity(id, timestamp);
            entities.add(testEntity);
        }

    private static List<IntegerIdEntity> createTestEntitiesInteger(int count) {
        List<IntegerIdEntity> entities = new ArrayList<IntegerIdEntity>();


        for (int i = 1; i <= count; i++) {
            long id = i;
            String milliseconds = new PrintfFormat("%03d").sprintf(i);
            Date timestamp = DateUtils.createDate("2011-06-01T14:00:00." + milliseconds);
            IntegerIdEntity testEntity = new IntegerIdEntity(id, timestamp);
            entities.add(testEntity);
        }
