13. printf argument list

• When printf has both format string and the argument list, the data is merged into formatted stream of tokens:

  
      int centimeters = 15;
      System.out.printf(
          "There are %.2f inches in %d centimeters.%n",
          centimeters / 2.54, // multiple arguments on argument list are separated by commas
          centimeters
          );
  
  

  Here, %.2f and %d are called format specifiers. The output is

  
      There are 5.91 inches in 15 centimeters.
  
  

• By default, there is a one-to-one correspondence between format specifiers and the arguments

• The first format specifier %.2f is matched with the first argument, which is the expression centimeters/2.54

• The second format specifier %d is matched with the second argument, which is centimeters

• The format specifier %n moves the insertion point to the beginning of the next line
