Left justification

By default, all output is right-justified. You can force output to be left-justified by placing a minus sign directly after the %. For example, %-10.2f left-justifies a floating-point number with two decimal places in a ten-character field. import java.util.*; public class MainClass {   public static void main(String args[]) {     Formatter fmt = new Formatter();     // Right justify by default.     fmt.format("|%10.2f|", 123.123);     System.out.println(fmt);     // Now, left justify.     fmt = new Formatter();     fmt.format("|%-10.2f|", 123.123);     System.out.println(fmt);   } } | 123.12| |123.12 |
