Getting String Representation of a Formatter Object of US Locale Example

The following example shows the usage of Java Formatter out() method to print the destination of a formatter. We've created a formatter object with a StringBuffer and US locale. Formatter is used to print a string using the format() method. Then its content is printed using toString() method.

package com.tutorialspoint;

import java.util.Formatter;
import java.util.Locale;

public class FormatterDemo {
   public static void main(String[] args) {

      // create a new formatter
      StringBuffer buffer = new StringBuffer();
      Formatter formatter = new Formatter(buffer, Locale.US);

      // format a new string
      String name = "World";
      formatter.format("Hello %s !", name);

      // print the formatted string with default locale
      System.out.println("" + formatter);

      // print the formatter as a string
      System.out.println("" + formatter.toString());
	  
      formatter.close();
   }
}

Let us compile and run the above program, this will produce the following result −

Hello World !
Hello World !
