allocating for array and then using constructor

Person.java ``` public class Person {     public String firstName, lastName;     public Person(String firstName,             String lastName) {         this.firstName = firstName;         this.lastName = lastName;     }     public String getFullName() {         return(firstName + " " + lastName);     } } ``` PersonTest.java ``` public class PersonTest {     public static void main(String[] args) {         Person[] people = new Person[20];              //this line .         for(int i=0; i<people.length; i++) {             people[i] =                  new Person(NameUtils.randomFirstName(),                         NameUtils.randomLastName());  //this line         }         for(Person person: people) {             System.out.println("Person's full name: " +                     person.getFullName());         }     } } ``` In above code, we used twice "new". Is this code is correct or wrong? First one is for allocation of array. But why the second one? It's from lecture notes.
