Usage

From source file:Main.java

public static void main(String[] args) {
    String s = "tutorial from java2s.com";
    try {/*from  www . j ava2  s. c  o m*/

        PrintWriter pw = new PrintWriter(System.out);

        // printf text with specified locale.
        // %s indicates a string will be placed there, which is s
        pw.printf(Locale.UK, "This is a %s program", s);
