public static void main(String[] args)
{
PersonManagement personManagement = new PersonManagement();
Person p1 = new Person(), p2 = new Person(), p3 = new Person(), p4 = new Person(), p5 = new Person();

Person[] persons = new Person[]{p1,p2,p3,p4,p5};
System.out.println("Persons in Array");

personManagement.displayAll();
System.out.println("Persons after Selection Sort");
personManagement.sort();
personManagement.displayAll();
System.out.println("Persons after Reverse of Array");
personManagement.reverse();
personManagement.displayAll();
