Nothing printing in my Console?

When I code anything that has console.printf("Anything");
nothing appears in the console.

I start with javac Filename.java then java filename

And still nothing will print. Sometimes I get an error < Could not find or load main class directory. >

Why is this happening?

Hi Adam,

have you imported a Console class? Do you have a main method .... ?

Can you give us your code, so we can look at it?

This is the code I am using:

import java.io.Console;

public class TreeStory {

public static void main(String[] args) {
    Console console = System.console();
    /*  Some terms:
        noun - Person, place or thing
        verb - An action
        adjective - A description used to modify or describe a noun
        Enter your amazing code here!
    */
    String name = console.readLine("Enter your name:   ");
    String adjective = console.readLine("Enter an adjective:   ");
    console.printf("%s is very %s", name, adjective);
}

}

Hi again :)

Here my code:

import java.io.Console;

public class TreeStory {

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 very %s", name, adjective);
   }
}

And my input into terminal:

treehouse:~/workspace$ javac TreeStory.java
// and then 
treehouse:~/workspace$ java TreeStory

The output is:

Enter your name:   Adan
Enter an adjective:   fancy
Adan is very fancy

I don´t know what I am doing different. But it works ....

Let me know if you could find the trick ....

Try to reload the workspace ...

Thanks Grigorij!
