Question

Can someone help me with my code.. I cant get an output. It says I do not have a main method. HELP PLEASE. The instruction are in bold on the bottom of the code.

package SteppingStones;

public class SteppingStone5_Recipe {

private String recipeName;

this.servings = servings;
}

/**

* 1. Modify this code to develop a Recipe class:
* a. change the void main method createNewRecipe() that returns a Recipe
*
* 2. FOR FINAL SUBMISSION ONLY:Change the ArrayList type to an
* Ingredient object. When a user adds an ingredient to the recipe,
* instead of adding just the ingredient name, you will be adding the
* actual ingredient including name, amount, measurement type, calories.
* For the Milestone Two submission, the recipeIngredients ArrayList can
* remain as a String type.
*
* 3. Adapt the printRecipe() method to print the amount and measurement
* type as well as the ingredient name.
*
* 4. Create a custom method in the Recipe class.
* Choose one of the following options:
*
* a. print out a recipe with amounts adjusted for a different
* number of servings
*
* b. create an additional list or ArrayList that allow users to
* insert step-by-step recipe instructions
*
* c. conversion of ingredient amounts from
* English to metric (or vice versa)
*
* d. calculate select nutritional information
*
* e. calculate recipe cost
