how I can rewrite this:
for (int i = 0; i < numberOfSpaces; i++) {
System.out.print(" ");
}
using String.format()?
PS
I'm pretty sure that this is possible but the javadoc is a bit confusing.

You need to specify the minimum width of the field.
String.format("%" + numberOfSpaces + "s", "");
Why do you want to generate a String of spaces of a certain length.
If you want a column of this length with values then you can do:
String.format("%" + numberOfSpaces + "s", "Hello");
which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.

in C I would write: printf("%.*s", numberOfSpacs, " "); without any string concatenation

Or, if you're feeling saucy, String.format(String.format("%%%ds", numberOfSpaces), "")

I know this is totally old but: is this possible for leading AND trailing spaces? I knwo that you use the "-" sign for trailing but I don't know if it's possible to combine them
int numberOfSpaces = 3;
String space = String.format("%"+ numberOfSpaces +"s", " ");
