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

Use String.format:

String.format("%.2f", 4.52135);

As per docs:

The locale always used is the one returned by Locale.getDefault().
