vsnprintf like

[stef]

Hello,

I would like to do my "own" printf.
Under C I used to play with the classic "vsnprintf" :

void print_it(char *app, size_t num, ...)
{
va_list arg;
char buf[1024];
...
va_start(arg, num);
vsnprintf(buf, ..., ..., arg);
...
}


How could I do that with Java ?


thanks for your help...

Using Java 5, the method header would look like:
void print_it(String app, Object ... args)

The args object would act like an array of Objects.

Why your "own", rather than a built-in one?

Under C I used to play with the classic "vsnprintf" :

Under 1.5 and later PrintStream has a format(String, Object...) method. This
is pretty close to the C printf methods. Or just use the java.util.Formatter
directly.
