Question

Java 1.6 String format

Asked by: sunray_2003

I want to format 30.5 to 00030.500 - Make the whole numbers to fill 5 spaces and decimals to fill 3 spaces. I dont want to use StringBuffers/for loops to format.

I am looking to see if if I can use String.format method.

System.out.println(String.format("%05d%.3f", Integer.parseInt("30"), Float.parseFloat(".5")));
000300.500

This places extra 0 next to 30 making it 300. I want to know if there is a format specifier to add zeros to the end of integers. Any other ideas for achieving the desired results is much appreciated.

Try something like

String s = String.format("%09.3f", d);

Why not use NumberFormat?

import java.text.*;
 
...
 
NumberFormat formatter = new DecimalFormat("00000.000");
System.out.println(formatter.format(30.5));
