JAVA double to string with sign and without trailing zeros

Question

I need to format a double value to string in such a way that it has a sign in front ("+" whether it's positive, "-" whether it's negative) and has no trailing zeros. For example:

Input: 1.5
Output: "+1.5"

Input: 1.0
Output: "+1"

Input: -123.123321
Output: "-123.123321"

Have you looked at String.format() and format strings?

I think this solution is cleaner:

DecimalFormat df = new DecimalFormat("+0.##############");
df.format(1.5);
