Javabean ituh just a convention...
But a very unique one at that... :p
Kalo liat di web nya sun (baca:oracle)... katanya java bean ituh plain old java
object...
Yang... harus punya constructor with no parameter,
dan beberapa naming convention of how the getter and setter method should be
named...
and nothing else...
Kenapa begini?
Banyak framework... (spring yang udah gue bongkar... dan banyak pake ini... )
Yang pake code macem gini nih...
Contoh concrete mungkin lebih kena yah...
class Student {
private String name;
//getter and setter
}
Ntar di pake dengan cara gini nih...
BeanWeapper student = BeanWrapperImpl(new Student()):
student.setPropertyValue("name", "Adelwin");
nah.. kliatan khan gunanya?
Dan kenapa convention ini dipake banget?
Jadi... class tersebut.. BUKAN javabean...
