Right padding with zeros in Java

Please try to read this doc, look if the library of apache commons StringUtils can help you

I've made a code like this :

import org.apache.commons.lang3.StringUtils;

public static void main(String[] args)  {   
  String str = "123";
  str = StringUtils.leftPad(str,10,"0"); //you can also look the rightPad function.
  System.out.println(str);
}

You could use:

String.format("%-5s", price ).replace(' ', '0')

Can I do this using only the format pattern?

String.format uses Formatter.justify just like the String.printf method. From this post you will see that the output space is hard-coded, so using the String.replace is necessary.

Try this :

String RightPaddedString = org.apache.commons.lang.StringUtils.rightPad(InputString,NewStringlength,'paddingChar');
