 data. A 

static

 method can directly access only 

other

static

 data defined by its class. It cannot operate on an instance variable of its 

class because there is no object to operate on.

For example, in the following class, the 

static

 method 

ValDivDenom( )

 is illegal:

class StaticError {

  public int Denom = 3; // a normal instance variable

  public static int Val = 1024; // a static variable

  /* Error! Can't directly access a non-static variable

     from within a static method. */

  static int ValDivDenom() {

    return Val/Denom; // won't compile!

  }

}

Here, 

Denom

 is a normal instance variable that cannot be accessed within a
