       public void display()

       {

              System.out.println("Name: " + this.Name +" ,Age: " + this.age);

       }

      

       public static void main(String[] args)

       {

              PersonManagement personManagement = new PersonManagement();

  •               Person[] persons = new Person[]{p1,p2,p3,p4,p5};

              System.out.println("Persons in Array");

              personManagement.set(persons);

              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();

              System.out.println("Persons with Even Ages");

              personManagement.displayEvenAgePerson();

              System.out.println("Persons with Odd Ages");

              personManagement.displayOddAgePerson();

              System.out.println("Persons with Prime Ages");

              personManagement.displayPrimeAgePerson();
