Predict the Output
Source files are here: AspectJExample4src.zip. If you need instructions on what do with these files, try here.
Have a look at the following Java files and, as before, predict the output.
Main.java
package ex4;
public class Main {
public static void main(String args[]) {
Address a = new Address();
Dao.save(a);
a.setZip(null);
Dao.save(a);
a.setZip("75001");
Dao.save(a);
Dao.save(a);
}
}Dao.java
package ex4;
public class Dao {
public static void save(Object o) {
if (o != null) {
System.out.printf("Saving: %s\n", o.getClass());
}
}
}Address.java
Address is unchanged from the previous example. It is a simple Java Bean style class with setters and getters. —-
