How to compare two objects in an array and replace it's values if they are equal

Question

For instance, I am creating and storing objects with three parameters (Bob, Marley, 55) with a Scanner in an array of objects and while input does not equal to stop it keeps storing. I need to find out while looping if the first name equals to any object's first name in an array if so I want to replace its age.

Thank you in advance!

According to my understanding, You can use a map where your key will be first name and the the object will be value. Pseudo code will be like.Let me know if I missed anything.

yourObject obj;
Map<String, yourObject> mapBasedOnFirstName = new Hashmap<>();

if (mapBasedOnFirstName.contains(obj.getFirstName)) {
yourObject obj2 = mapBasedOnFirstName.get(obj.getFirstName);
obj2.setAge(obj.getAge);
}
