Usage

From source file:Person.java

public static void main(String[] args) {
    Person[] authors = { new Person("A", "B"), new Person("C", "D"), new Person("E", "F"), new Person("Z", "Y"),

    Arrays.sort(authors);
    System.out.println("\nThe cast is ascending sequence is:\n");
    for (Person person : authors) {
        System.out.println(person);
    }/*  w w w  .  jav  a2 s . c om*/
