I am having trouble with the following problems in this Java code:

1. I am unable to get menu item #3 to display the objects in the ArrayList ListOfRecipes

2. I am unable to elicit user input on the chosen recipe because it always defaults to the first recipe instead of the one created by menu item #1 (create new recipe)

3. For menu item #4, adjust recipe servings, I need to get the ingredients and the ingredient amount to adjust the ingredient amount per serving but am unable to get that to display to calculate the new servings, ingredient, adjusted ingredient amount.

Here is the code:
