java - "cannot find symbol " error in oop pig game -

i doing oop pig game. in encounter error: "cannot find symbol class name". can please me finding it.

 public class player   {     protected string name;     scorekeeper sk;     // sk =  new scorekeeper();      public player(string name)     {       this.name = name;       //scorekeeper sk = new scorekeeper();       sk = new scorekeeper();     }      public player(){  }      public int getscore()     {        return sk.getgametotal;     }      public string getname()     {        return name;     }      public int incscore(int rollvalue)     {        sk.addtoroundtotal(rollvalue);        return sk.getroundtotal;     }      public int setscore()     {       return sk.resetroundtable();     }   }     

this class create object class scorekeeper , other class is

public class scorekeeper {      int gametotal = 0;     int roundtotal = 0;      public scorekeeper()      {         //gametotal = 0;         //roundtotal = 0;     }      public void addtogametotal() {         gametotal += roundtotal;         resetroundtotal();     }      public void addtoroundtotal(int value) {         roundtotal += value;     }      public void resetroundtotal() {         roundtotal = 0;     }      public int getroundtotal() {         return roundtotal;     }      public int getgametotal() {         return gametotal;     }   }  

when try compiling class

        player.java:5: cannot find symbol         symbol  : class scorekeeper         location: class player         scorekeeper sk;         ^       1 error 

in player-class wrote:

scorekeeper sk; 

the "k" needs upper case this:

scorekeeper sk; 

java case-sensitive language
