Could someone explain what is the error in this program?

public class Animal extends SimpleElement
{
public final static int MAMMAL = 1;
int animalClass;

Have you complied this program? What compiler says? What's the error, If you post the error, then its easy for Ranchers to explain the cause of error . And Please use Code Tags

Other than the fact that the classes SimpleElement and FoodRecipe aren't defined here (and they'd need to be for this code to compile) I don't see any outright errors.
