printf or println

In the video of Exceptions (Java, Craig Dennis) there is the part about when you put in too many PEZ. The following is written:

System.out.println(“Whoa there!); System.out.printf(“The error was: %s\n”, iae.getMessage());

I think somewhere in the course I missed something, cause I don't get the difference between println and printf. So is there anyone who can tell me the difference and when you use println and when printf?? Thank you!

Hi Jari,

printf prints a formatted string - that's why you can use %s and a load of other formatters within your output string.

println just prints out some text with a new line.

I hope that helps,

Steve.

Here is some helpful documentation on how the formatter works.
