Why do I get this error in Eclipse?
import java.io.Console;
public class HelloWorld {
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);
}
}

10,359 Pointsyou can't use Console in Eclipse you have to use Scanner instead
import java.util.Scanner;
public class HelloWorld {
public static void main(String[] args) {
Scanner scanner= new Scanner(System.in);
/* 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!
*/
System.out.println("Enter your name: ");
String name = scanner.nextLine();
System.out.println("Enter an adjective: ");
String adjective = scanner.nextLine();
System.out.printf("%s is very %s", name, adjective);
}
}
