Introduction

The following sections use 's' as the conversion character for the format specifiers.

The 's' conversion formats its argument as string.

For the following code 

System.out.printf("%s, %s, and %s", "Java", "Json", "Javascript");

its output: 

Java, Json, and Javascript

Syntax

A format specifier can refer to an argument in three ways:

  • Ordinary indexing
  • Explicit indexing
  • Relative indexing

Demo

public class Main {
  public static void main(String[] args) {
    System.out.printf("%s, %s, and %s", "Java", "Json", "Javascript");
  }/*w ww  .  j av  a  2  s.  c om*/
}
