what's the difference between println and print? Both are used one after the other and seem to do the same thing

println("Sample String") will print the text string but will then move the curser to a new line. print("Sample String") will also print the line but will not move the curser to the next line. This results in all subsequent print commands being printed on the one line. You'll find println is used much more throughout the course.

I understand. I think part of the confusion is that in the "playground" section it adds a new line to both anyway, the only difference is in the output section.

The prime distinction to be made between the print and println() functions is that the println function adds a line break after printing out the output statement whereas the print command will not do so.

Consider:

print("Hello")
print("Hello Again!!!")

The console output in the assistant editor would be:

HelloHelloAgain!!!

The same statements with println used in place of the print commands would yield the following output:

Hello HelloAgain!!!
