allocating for array and then using constructor

Question

Person.java

public class Person {
    public String firstName, lastName;

    public Person(String firstName,
            String lastName) {
        this.firstN         


        

Answer 1

Yes, it is correct.

The line:

Person[] people = new Person[20]

allocates the array, full of references to null while the line:

new Person(NameUtils.randomFirstName(),
                      NameUtils.randomLastName());  //this line

fills it [the array] by instantiating objects of type Person, and assigning the reference in the array.
