如何使用equals方法比较不同类中的对象数组

Question

public boolean equals(Object obj) {
    boolean result = false;
        if (obj instanceof Recipe) {
           Recipe that = (Recipe) obj;
            if(this.getName().equals(that.getName())){

            for (int cnt = 0; cnt < I.length; cnt++) {
                if (I[cnt].getName().equals(that.getName())) {

                result = (this.getName() == that.getName());
        }
             }
    }
    }
    return result;

}

I can compare the name of the recipe and once they are equals I need to compare one by one the ingredients but I do not know how to do the comparison. I know I need a for loop which I added it to compare all the ingredients, but what to do after that. I would really appreciate any type of help.

Answer 1

override equals() in Recipe, as it looks you are trying,

then you have to compare each field of Recipe

But you shoul post the source of the fields of Recipe

Answer 2

The List equals checks for references to equal objects in the same order, which may be what you need. If so, consider Arrays.asList which gives you a List view of an array of references.
