Whats the difference in Java between these two? ("My name is %s", name), ("My name is %d", name). Also what's the difference in \n or %n in creating a newline in code. If there is none why do we have both.

re: So %n and \n are the same? and if so why have two different ways?
it really a matter of usage.
printf (f stands for formatted) needs the formatting information, and the %s, %d, %n .... provide this information. It great for readability
if you put /n in the string, then you probably get away with println. You will get the the line break, but you will loose the readability that comes with printf
there is no right/wrong here ... just use as needed.
hope this helps

14,132 Points%s is to prnt a string
%d is generally used to print a number
%n is for new line
Here is an example.
System.out.printf("Hello there, I am %s and I am %d yrs old %n", "Jimmy", 99);
if this answers your question, please mark the question as answered.

9,844 PointsMilka Vuorio I thought the same thing and this I believe is the best explanation on the internet: http://stackoverflow.com/questions/1883345/whats-up-with-javas-n-in-printf I know this is an old post but I thought I'd post it to help people out. Also %d is used to print decimal numbers I know it can be used to print integers but why use it when this %i has been made to specifcally print integers?
