Newbie questions about lesson on class implementation

[Jonnybravo9]

Hey everybody,
I have been learning Java onlin for about a week now.
here is the program I am trying to get to work

class OfficeLights {
 
      char Status = Off;
      char Status = On;
      void changeStatus(char newValue) {
           status = newValue;
      }
 
      void printStates() {
           System.out.println("Status:"+Status);
      }
} 
 
class CoffeeMug {
 
      char lid = Open;
      char Lid = Closed;
      char Contents = Empty;
      char Contents = Coffee;
      char Contents = Tea; 
 
      void changeLid(char newValue) {
           lid = newValue;
      }
 
      void changeContents(char newValue) {
           Contents = newValue;
      }
 
      void printStates() {
           System.out.println("lid:"+lid+" Contents:"+Contents);
      }
}
 
class OfficeLightsCoffeeMug {
    public static void main(String[] JD) {
 
 
      OfficeLights light1 = new OfficeLights();
 
      light1.changeStatus(On);
      light1.printStates();
 
 
      CoffeeMug mug1 = new CoffeeMug();
 
      mug1.changeLid(Closed);
      mug1.changeContents(Coffee);
      mug1.printStates();
      }
}

It wont compile, I get 14 error messages.
I have attached a screenshot of the errors I am getting when I try to compile.
Any advice on this particular program &| some newbie tips/advice in general would be very welcome,
Thanks!
P.S. I hope this is the right topic to post under, sorry if I commited a faux pas...

For starters,

char Status = Off;

is not a proper statement. char is a primitive whose syntax is:

char status = 'o';

If you just want something to store an off/on value, look into using a boolean
