In-Depth Information
The meaning of flags, width, and precision is similar for the different
conversions but the details differ depending on the exact kind of con-
version, as discussed in the following sections.
When you consider which argument types are expected for each con-
version, remember that anything that applies to a primitive type also
applies to its wrapper. For brevity we don't mention the wrapper classes
explicitly.
22.1.2. Integer Conversions
The integer conversions apply to arguments of type
byte
,
short
,
int
, and
long
. The different conversions are
•
d
decimal format
•
o
octal format
•
x
,
X
hexadecimal format
The width value specifies the minimum number of characters to out-
putincluding additional characters that the flags may cause to be in-
cluded. No precision value may be given. The flags applicable to each
conversion are shown in the following table. An entry with a x means
the flag is not allowed.
Flag
