12. Formatting Output with printf

• Two oveloaded methods printf yield output on the standard output device:

  
      System.out.printf( formatString );
      System.out.printf( formatString, argumentList );
  
  

• Here, formatString is a string specifying the format of the output, and argumentList is a list of arguments.

• The argumentList is a list of arguments that consists of constant values, variables, or expressions

• If there is one argument, the output is similar to System.out.print():

  
      System.out.printf( "Hello there!" ); // uses only the format string
  
  

• NOTE: String method format also uses syntax similar to printf
