public static void main(String[] args) {

Name n1 = new Name("Narges", "Norouzi");

Name n2 = new Name("Jane", "Prohrammer");

System.out.println(n1);

System.out.println(n2);

System.out.println(n1.initials());

System.out.println(n2.initials());

}

Name.java

public class Name {

private String firstName, lastName;

public Name(String firstName, String lastName) {

this.firstName=firstName;

this.lastName=lastName;

}

public String toString() {

return lastName+", "+firstName;
