BlueJ Noob!!! Need some help writing some codes

-----------------------------------

Ok so this was a lab in class that I couldnt quite grasp.....they want me to create a public boolean for a FancyInt Object being a positive number....Everything I completley made from scratch and the only other parameters are the get value, set value, FancyInt, initialValue, and then it asks a few more questions where I get stuck at so here it is.....

   c. A feature that returns whether or not a FancyInt is positive.
   The class should implement this feature via a method with 
   the following skeleton:

 public boolean isPositive ()
   {
      boolean result;

      result = true; // dummy result initialization; ??? FIX ME
  
      return true; 
   } // isPositive



d. A feature that returns whether or not this FancyInt object is even.
   Please use a method signature similar to the one used for isPositive.

   e. A feature that views the value of this FancyInt object as a temperature 
   in degrees Celsius and returns its Fahrenheit equivalent.
   The class should implement this feature via a method with 
   the following signature

Also they want me to create a method so I can turn a value into Celsius but have it returned as Fharenheight...and vice versa.... any suggestions would be appreciated.

so given some value (e.g. 4), how do you know if it's positive or not?

C  x  9/5 + 32 = F

(F  -  32)  x  5/9 = C

Just use these calculations inside the method that you are using for the conversions.

For the first question (determine whether fancyInt is positive), use a command that checks to see if the number is greater than 0 or less than 0.
