Double decimal formatting in Java

Question

I\'m having some problems formatting the decimals of a double. If I have a double value, e.g. 4.0, how do I format the decimals so that it\'s 4.00 instead?

Answer 1

double d = 4.0;
DecimalFormat nf = DecimalFormat.getInstance(Locale.ENGLISH);
System.out.println(nf.format("#.##"));
