Kind of stuck

[Nicky Swans]

Hey guys I have been doing an assignment first time I have used Java and I am not sure why my while statements dont seem to work? What I am trying to do is to re-ask a user a question if they enter a false answer. There are only two correct answers blue or white and if they enter purple I want it to be re-asked. Could anyone give me some help with this?

    System.out.println("Please choose a colour, blue or white?");
    colour = scanner.nextLine();
    colour = colour.toLowerCase(); // Changes the case of the String colour to lower case rather than ignoring it

if (colour.equals("white"))
      {
         System.out.println("Hello " + forename + " " + surname + ", Swansea City play in white.");
      }
      else if (colour.equals("blue"))
      {
         System.out.println("Hello " + forename + " " + surname + ", Cardiff City play in blue.");
      }
    else 
      {
         System.out.println("Sorry," + forename +", I did not understand you");
    }
  }
}

Thanks, complete newb to java I rarely ask for help when it comes to things but this is something that confuses me.

If you could, please post the whole thing

Hi,

Instead of

colour.equals("white")

try

colour.compareTo("white") == 0

What is the benefit of doing this?

I don't see any while statements in your code ...

Hi,

What is the benefit of doing this?

Because compareTo compares the text.
I am using this and it works

The compareTo( ... ) methods compares two ordered objects o1 and o2 where o1 < o2 or o1 == o2 or o1 > o2. The equals( ... ) method just checks whether o1 == o2 or o1 != o2. The second approach should be enough for the OP's problem.

It may work, but how does using a method intended for ordering (compareTo) make more sense to use when looking at equality than a method (equals) that simply handles equality?

There is not.
I thought that that was the question.
I have tested the code and the code is working fine.
So JosAh is correct, where is the while statement because the rest is working.
