Priority quene based on argument of person class

Question

Hey I've class called person that looks like below

PersonClass[] person= {
            new PersonClass(90234234434L, "Name", "Surname", Age, "Street", Priority),
            ...
            ...
    };

Then I create array

 ArrayDeque<String> arrayDeque = new ArrayDeque<>();

edit: my mistake, I'm already using

PriorityQueue<String> priorityQueue = new PriorityQueue<>

I tried many ways but I cant solve, how to sort this person array by priority value. If something is unclear, ask. Thanks for help in advance.

Answer 1

You can sort your PersonClass objects using Comparable.

First you have to implements Comparable in your PersonClass and override the compareTo method like below,

@Override
public int compareTo(PersonClass person) {
    return this.Priority - person.Priority;
}

Then you can sort the person array in your method using sort method in Arrays

Arrays.sort(array)
