Dynamically formatting a string
- by TofuBeer
Before I wander off and roll my own I was wondering if anyone knows of a way to do the following sort of thing...
Currently I am using MessageFormat to create some strings. I now have the requirement that some of those strings will have a variable number of arguments.
For example (current code):
MessageFormat.format("{0} OR {1}", array[0], array[1]);
Now I need something like:
// s will have "1 OR 2 OR 3"
String s = format(new int[] { 1, 2, 3 });
and:
// s will have "1 OR 2 OR 3 OR 4"
String s = format(new int[] { 1, 2, 3, 4 });
There are a couple ways I can think of creating the format string, such as having 1 String per number of arguments (there is a finite number of them so this is practical, but seems bad), or build the string dynamically (there are a lot of them so this could be slow).
Any other suggestions?
