class SampleClass {
   int a;
   int b;
   AnotherClass q;

   public void sampleMethod()
   {
         int c = 1;
         a = c * 7;
         b = 32 + c * a;
   }
}

which of the following statements is true?

        'c' is a reference.
        'a' and 'b' are local variables.
        'a' and 'b' are declared as a primitive data type.
        'q' is declared as a primitive data type.

Having a bit of trouble with this one.... thanks in advance!

c. 'a' and 'b' are declared as a primitive data type.

primitive data types are int/long int/short int/char/boolean/float/double, (non-primitive can be any class composed of other classes and/or primitives - ie. a class is a non primitive data type).

-q isn't delcared as a primitive type because it is declared as a class.

-a and b are not local variables because they are declared outwith a method (local variables are declared inside a method and go out of scope after the method exits).

-depends on your definition of reference but c is declared as an int with the value one and so it holds '1' and does not refer to another object.
