Question

I have to make a constructor for an ArrayList. So basically what I want is that this constructor makes an ArrayList.

    public Recipe(String[] modifications){

The problem is, it should give something like(example):

String[] modifications = [heatup, cooldown, mix, heatup]

Will the constructor work like this:

    Recipe(heatup, cooldown, mix, heatup)

or do I need to change it to somethign like:

    Recipe(modifications){
    this.myArrayList[1] = modifications[1]
    .
    .
    .
    }

thank you and sorry if there are some big mistakes in my code, still learning my Java code.

Answer 1

You can define it this way:

public Recipe(String... modifications)

This will give you a variable argument list, so your constructor will work like this: Recipe(heatup, cooldown, mix).

Inside of the constructor, you can use it just like an array.
