"System.out.printf" or "console.printf" ?

I'm using an IDE to practice, which is working just fine with other languages. However, I sometimes find it difficult to complete exercises with Java. Should I use "System.out.printf" or "console.printf" ? It seems that both work occasionally, but not always, which is a bit annoying. The set up below is currently working, but I don't want to have to adjust every new challenge. 

import javax.accessibility.*;
import java.io.*;
import java.io.Console;
import javax.lang.model.element.*;
class Untitled {
    public static void main(String[] args) {
        Console console = System.console();
        String name = console.readLine("Enter your name:  ");
        String adjective = console.readLine("Enter an adjective:  ");
        console.printf("%s is a very %s man", name, adjective);
    }
}

Cheers.

Hi Arnaud, I formatted you code so it is easier for people to read. Hope you get an answer!

Hello arnaud,

Perhaps you have already found an answer to your question, but perhaps the thread below might explain why it's not always working:

Thanks Caleb,

"System.out.println" is working, and so are "System.out.printf" or "console.printf", but they don't work all the time, so I have to switch from one to another sometimes, which is not ideal. What is the difference between all three, and is there one that is always guaranteed to work in all IDEs?
