Error: float cannot be dereferenced

[Rahul mir]

Hi,
please someone explane the error :
Error: float cannot be dereferenced, in the following code.

class Autobox2 {
  public static void main(String[] args){
    Float A=9.0F;
    float a =(float)9.0;
    System.out.println(A.equals(a));
    System.out.println(a.equals(A));
    System.out.println(a<=A);
    System.out.println(A<=a);
  }
}

look at line 6 . you cant call method on primitives.

[Rahul mir]

ya, we can't call method on primitive .. but in error message, float cannot be dereferenced.. dereferenced thing i am not getting.

[Seetharaman Venkatasamy]

dereference - finding an appropriate object via reference. here you cant find object since float is a primitive, hence error.

[Rahul mir]

Ok, got it.. here equals method try to find the value of primitive type variable, from it's reference, that's why dereferenced error came..

thanks.
