Hello, this is for class intro to object oriented java programming. This project is a recipe collection manager with 3 classes (Ingredient, Recipe & Recipe_Box) and a main driver class (UnitTest). Im showing some errors in the program and I cant figure out why. We've been working on this project all semester and I think I have some code in the wrong spot. Im not sure. My question is if you can overlook this and tell me what I am doing wrong. Next, I need change the nameOfIngredient from an ArrayList to an object so that all the steps will playout when a user adds an ingredient to the list. Last, I need to add an ArrayList of instructions. Only problem is we covered Arrays like 7 weeks ago and I cant remember where to put it and how to execute it. The following is a pseudo-code I code for the ArrayList. Feel free to change it. Please let me know what I did wrong for this too. After the psuedo-code I will add the class files and the main last so you can take a look at the code I have so far. Thank you in advance.

Pseudo-code Instructions

public static addInstructions() {

String steps = (""); // string type

ArrayList Instructions = new ArrayList(); // accepts new list for instructions

boolean addMoreSteps = true; //Boolean value closes or continues list

int i = 0; // declares use of the int i printing method.

System.out.println("Please enter the instruction: "):

String Instructions = scnr.nextLine();

do {

System.out.println("would you like to continue to add steps (y or n)? ");

String reply = scnr.next().toLowerCase();

if (reply.equals("y")){

addMoreSteps = true;

Instructions.add(steps);

}

else{

addMoreSteps = false;

break;

}

while (addMoreSteps == true);

for (i = 0; i < Instructions.size(); i++){

System.out.println(Instructions.get(i));

}

}

}
