What are the methods for the console object?

It's asking me to prompt for input from the user, but its been a few days since ive done an exercise, and I cant remember what the method is that I can call to get the response. What is it?

The method you're thinking of is the 'readLine();' method, and you invoke it off of a console object.

If you wanna read more about the Console class(which will give you detailed info about the other methods offered from the Console class can be read here: https://docs.oracle.com/javase/7/docs/api/java/io/Console.html

I'm not sure if there were any changes made, I doubt there were, but just in case. Here's a link to the Console docs for Java SE8. (The first link is the to the Java SE7 Console class docs): https://docs.oracle.com/javase/8/docs/api/java/io/Console.html

import java.io.Console;

public class ConsolePractice {
    public static String name;
    static Console console = System.console();

    public static void main(String[] args) {
        name = console.readLine("What is your name?: ");  //readLine(); prompts for the user input,
                                                          //and returns it as a String.
        System.out.println("The name typed in was: " + name);
    }
}

Let me know if you have any other questions.
