Почему у person[] personarray есть проблема?

---

error: cannot find symbol

Что я уже пробовал:

import java.util.Scanner;
import java.util.Date;

public class Assignment
{
	static Scanner key  = new Scanner(System.in);
    private Person[] personArr = person();
    private static int indexNum = 0;
    
    public static void person()
	{
	    Person[] personArr = new Person[10000];
		personArr[0] = new Staff("xxx",'F',"01110807822","xxx123","xxx");
		personArr[1] = new Staff("xxx",'F',"0123456789","xxx123","xxx");
		
		return personArr;
    }
	public static void staffDisplay(String[] personArr)
    {
    	for(int i = 0; i < personArr.length; i++)
        {
        	if(personArr[i] != null)
           	{
           		if(personArr[i] instanceof Staff)
           		{
           			System.out.println(personArr[i]);
           		}
           	}
        }
     }
