In Java, can I use the precision specifier for integers?

Question

While using System.out.printf in Java, can I use the precision specifier to format an integer variable, such that it prepends the integer with zeros? If yes, how?


I need to get an output like

+0061

(such that 61 is the integer and the + sign is forced and the two zeros are prepended by the precision specifier)
and I tried using

System.out.printf("%+.4d" , number);

but it throws an exception to me at runtime.
