Question

What's the purpose of putting System.out.println() under the main method, because the code still works without it?

Answer 1

Could you give us the context of this question? I assume you are asking about Lab 1 Project 3, but I don't know for sure.

System.out.println() will print a blank line into the console and move the cursor to the next line. The purpose of printing a blank line in this context is to create spacing between your letters, making them easier to read (and look a lot nicer). Sure, your code will still work without printing blank lines, but the overall goal is to create a readable output, which is why they are encouraged.

Your answer hits my point. Thanks!

Answer 2

It is the same as using \n which is used to get to a new line but it better to use it out of the main method if possible to avoid redundancy!
