What is the difference between java.io.console and scanner. Looks like io console don't work in Eclipse.

I am trying to understand the console concept here. I understand it is a class and need to import the io console. What is the difference between console and scanner. Secondly, why we cannot use it in IDE like Eclipse.

If I am not mistaken, IDE Eclipse using something called javaw which console commands will not work with. Instead, you must use the Scanner class if you are using Eclipse. I have worked out the TreeStory example (Java Basics) from this course in Eclipse if you still need any help. I tried to snapshot my workspace but ran into problems so here is the raw code(sorry if the formatting is bad):

import java.util.Scanner;

public class EclipseTreeStory {

public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);

    System.out.println("What is your first name? "); // prompts for first name input
    String firstName = scanner.nextLine();

    System.out.println("How old are you? "); // prompts for user age input
    int age = scanner.nextInt();
    // String ageAsString = Integer.toString(age); //Converts 'int age' to a String
    // variable
    if (age < 13 || age > 21) {
        System.out.println("You must be at least 13 to use this program. Exiting....");

    System.out.println("Enter and adjective: "); // prompts for adjective input
    String adjective = scanner.next();

    String noun;
    boolean isInvalidWord;
    // The do-while loop looks for illegal words to use...dork and jerk in this case
    do {
        System.out.println("Enter an noun: ");
        noun = scanner.next();
        isInvalidWord = noun.equalsIgnoreCase("dork") || noun.equalsIgnoreCase("jerk");
        if (isInvalidWord) {
            System.out.print("That language is not allowed.  Try again... \n \n");
    } while (isInvalidWord);

    System.out.println("Enter a verb ending in -ing:  "); // prompts for verb input
    String verb = scanner.next();

    System.out.println("Enter an adverb: "); // prompts for adverb input
    String adverb = scanner.next();

    // Takes in the input variables and creates the final Tree Story output
    System.out.printf("Your TreeStory:\n---------------\n");
    System.out.printf("%s is a %s %s. ", firstName, adjective, noun);
    System.out.printf("They are always %s %s.\n", verb, adverb);
