Document

Writes a formatted string to this output stream using the specified format string and arguments.

Usage

From source file:Main.java

public static void main(String[] args) {
    String s = "from java2s.com";

    PrintStream ps = new PrintStream(System.out);

    // format a string
    ps.format(Locale.UK, "This is a %s program", s);

    // flush to see the string
    ps.flush();//w ww .  j ava 2 s .  c  o  m
