Usage

From source file:Main.java

public static void main(String[] args) {

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

    // format a new string
    String name = "from java2s.com";
    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());
}
