Java decimal formatting using String.format?

Question

I need to format a decimal value into a string where I always display at lease 2 decimals and at most 4.

So for example

\"34.49596\" would be \"34.4

Yes you can do it with String.format:

String result = String.format("%.2f", 10.0 / 3.0);
// result:  "3.33"

result = String.format("%.3f", 2.5);
// result:  "2.500"
