Reflecting on a Class
This section will demonstrate the features of Java reflection that enable you to get the description of a class, such
as its package name, its access modifiers, etc. You will use a
Person
class as listed in Listing 3-3 to demonstrate the
reflection features. It is a simple class with two instance fields, two constructors, some methods, and it implements
two interfaces.
Listing 3-3.
A Person Class Used to Demonstrate Reflection
// Person.java
package com.jdojo.reflection;
import java.io.Serializable;
public class Person implements Cloneable, Serializable {
private int id = -1;
private String name = "Unknown";
public Person() {
}
public Person(int id, String name) {
this.id = id;
this.name = name;
}
public int getId() {
return id;
}
