Hello

the f in printf is "Formatted"

print f allows you to format your print statement. LEt take a look at this:

String firstName = "Mark"; String food = "Pizza"; int times = 5;

System.out.println("%s loves to eat %s%n%d times a day", firstName , food, times);

or you could do

System.out.println(firstName + " loves to eat " + food + "\n" + times + " times a day" );

Both will do the same thing ... but the first one is more elegant. I can look at it and tell the types of the arguments (String, and int) without having to scroll up the code to find the type.

it a matter of taste.

I typed this mind to screen ... there maybe some typos ... but I think you got the idea.

If this answers your question, please mark as answered.
