import java.io.Console;
public class forLoop { public static void main(String[] args) { Console console = System.console(); for (int i = 7; i > 0; i--) { console.printf("%d bottles of milk on the wall... %n",i); } } }
Output 7 bottles of milk on the wall... 6 bottles of milk on the wall... 5 bottles of milk on the wall... 4 bottles of milk on the wall... 3 bottles of milk on the wall... 2 bottles of milk on the wall... 1 bottles of milk on the wall...
What do %d and %n mean?

Courses Plus Student 8,592 Points%n is a placeholder for a new line (it will put a line break in the console print)
%d is a place holder for an integer (in this case, i will be placed into that point in the string)
console.printf("%d bottles of milk on the wall... %n",i);
if i is 7 will print the following to the console:
7 bottles of milk on the wall...
followed by a line break so the next loop will print to the next line in the console.
