How to use System.out.println()
It prints to the terminal window, which will open if System.out.println() executes.
If you can't see the terminal window,it might have appeared behind other windows (eg the main Greenfoot window). Minimize or move them to check.
System.out.println just works in Greenfoot and not in its jar. - Version.
If you want to use something similar in .jar you could do this:
GreenfootImage text = new GreenfootImage(x-size, y-size);
setImage(text);
text.drawString(".....YOUR...TEXT..........");

This creates an Image on which you can write sth. using drawString("");
Actually, the quickest way as of the latest version of Greenfoot to write text on a background is to use the new constructor in GreenfootImage here. That way you don't need to worry about wrapping and suchlike which isn't always the most straightforward of tasks.
I noticed that you can pass a 'newline' character to the GreenfootImage constructor you mention.
What would the code look like, passing a 'newline' character?
Something like:
For readability you might prefer:
... or similar.
import java.awt.Color; /* at the top of the file */
...
GreenfootImage textImage = new GreenfootImage("First line\nSecond line\nThird line", 12, Color.WHITE, Color.BLACK);
...
GreenfootImage textImage = new GreenfootImage("First line\n"
+ "Second line\n"
+ "Third line", 12, Color.WHITE, Color.BLACK);Thank you, Davin!
Since I am fairly new to Java programming, it seems there is a lot I am not aware of within the language.
But, I thank the good Lord that there are people who are willing to help; even if it's in the form of an answered question.
Evidently, the backslash character cannot be output as part of the text, because it is used to signal the compiler that a control character is forthcoming. Are there any other characters that can be called in this fashion (using the '\' char)?
And if so, what are they (code and description)?
EXAMPLE: \n = 'newline' (line feed/carriage return)
