1,184 Pointsbash: Greeter.java: command not found?
For some reason, it gives me the message "bash: Greeter.java: command not found" when I run the code. Did i do something wrong? Here's my code:
import java.io.Console;
public class Greeter {
public static void main(String[] args) { Console console = System.console();
String place = "Walmart";
String firstName = console.readLine("What is your first name: ");
console.printf("Hello %s! Welcome to %s. %n" , firstName , place);
}
}

To run the program you need to first compile it using "javac Greeter.java" and then run it with "java Greeter"

Console console = System.console();
Additionally, try starting your console with
treehouse:~/workspace$ clear && javac Greeter.java && java Greeter
Finally, I notice your final line has spaces BEFORE and after commas. You only need spaces AFTER commas.
Hope this helps!

Courses Plus Student 170 PointsYou did run command correctly? after you saved your file. I mean: javac <name>.java && java <name>
