Why does it not ask me for input?

import java.util.Scanner;

class Tutorial {
    public static void main (String args[]){
        System.out.println("Who goes there?");
        Scanner name = new Scanner(System.in); ## I am asking for input form user but it does not take imput
        if (name.equals("me") || name.equals("Me") ){
                System.out.println("Well, good for you smartass.");
        }else System.out.println("Well good meet");
        }
    }

Why does the program run the else and not ask for my input?

You merely created a Scanner but did not tell it to read something from the standard input. You can do that by calling scanner.next() to read a token scanner.nextLine() to read a line, etc. As well you are comparing a Scanner to a String in the if-statement.

import java.util.Scanner;

class Tutorial {
    public static void main (String args[]){
         System.out.println("Who goes there?");
         Scanner s = new Scanner(System.in);
         String name = s.next(); // get the token
         if (name.equals("me") || name.equals("Me") ){
            System.out.println("Well, good for you smartass.");
         } else System.out.println("Well good meet");
    }
}

You've only created an instance of the Scanner object. You need to invoke a method such as Scanner#nextLine() to read input and then compare the read value to "me" or "Me".

Example:

Scanner name = new Scanner(System.in);
String input = name.nextLine();
if (...) // Compare input to something here.

You might want to use String#equalsIgnoreCase for case-insensitive matching too.

You should read your input by using scanner.nextLine():

Scanner scanner = new Scanner(System.in);
String name = scanner.nextLine();
if (name.equals("me") || name.equals("Me"))
{
    System.out.println("Well, good for you smartass.");
} else {
    System.out.println("Well good meet");
}
scanner.close();
