Using a not equal operator in Strings

Question

I am trying to make a program that inputs the user's name and age and then asks the user on what info he/she wants to know. Here's the program :

import java.util.Scanner;
public class name_and_age {
    static Scanner key = new Scanner(System.in);
    public static void main(String args[]) {
        String name = "NAME";
        String age = "AGE";
        System.out.println("What is your name?");
                String a = key.nextLine();
                System.out.println("What is your age?");
                int b = key.nextInt();

                while()
                {
                    System.out.println("What do you want to know?");
                    String i = key.nextLine();
                if(i.equals(name))
                {
                    System.out.println("Your name is "+ a);
                }
                if(i.equals(age))                   
                {
                System.out.println("Your age is" + b);

                }
                else
                {
                    System.out.println("Please either enter age or name");
                }







    }

}
}

I am confused on what to put in the while loop because I want something like
while( (i.equals(name)) || (i.equals(age)) ) except that I want to put not equals in the place of equals. What should I do?

while(( ! i.equals(name)) || (! i.equals(age))) the ! is a not operator — c0der

You should format your code properly when posting it to StackOverflow — MC Emperor

To put not-equals, you use:

(!string1.equals(string2))

Note the ! in front. That turns whatever follows into the negation of whatever follows. ! true will be false and ! false will be true.
