Following is the class of Person:

public class Person {

       private String Name;

       public int age;

      

       public void set(String Name, int age)

       {

              this.Name = Name;

              if(age > 0 && age <= 100)

                     this.age = age;

              else

                     this.age = 1;

       }

      

       public void display()

       {

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

       }

      

       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();

              p1.set("Asad", 103);

              p2.set("Ali", 17);

              p3.set("Usman", 16);

              p4.set("Raees", 18);

              p5.set("Mujeeb", 15);

              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();

       }

}

Output of the Main method is:

Persons in Array

Name: Asad ,Age: 1

Name: Ali ,Age: 17

Name: Usman ,Age: 16

Name: Raees ,Age: 18

Name: Mujeeb ,Age: 15

Persons after Selection Sort

Name: Asad ,Age: 1

Name: Mujeeb ,Age: 15

Name: Usman ,Age: 16

Name: Ali ,Age: 17

Name: Raees ,Age: 18

Persons after Reverse of Array

Name: Raees ,Age: 18

Name: Ali ,Age: 17

Name: Usman ,Age: 16

Name: Mujeeb ,Age: 15

Name: Asad ,Age: 1

Persons with Even Ages

Name: Raees ,Age: 18

Name: Usman ,Age: 16

Persons with Odd Ages

Name: Ali ,Age: 17

Name: Mujeeb ,Age: 15

Name: Asad ,Age: 1

Persons with Prime Ages

Name: Ali ,Age: 17
