编译Java错误，无法使构造函数正常工作

Question

I am trying to code a simple bit of java but i cannot get it to compile I have defined the objects within my class as so

    public class teams
    {
      public char sponsor;
      public char tires;

I am trying to set the default value of class sponsor to N/A

      public teams()
      {
      this.sponsor = "N/A";
      }

Can anyone figure out why it wont work? Im fairly new to java and i know this is probably extremely simple, any help would be appreciated!

EDIT So thanks to Kevin Esche, I managed to get it to compile by using,
this.sponsor = 'N';

How would I get the term N/A instead of just N? Would I use unicode?, and if yes how do you format it?

Answer 1

Either you make your sponsor a String

 public String sponsor;

Or you store only one character in it:

    sponsor = 'X';

Good Luck.
