Private Double incentive = new Double("12345.567") Īlthough I have written the java docs for this class, still it is worth to explain you a little. It is just like a back door entry to get the values.
Of course it is a round about way and it is not a direct approach. But it is still possible using reflection. It is a violation of the object oriented concept. Case-I : Accessing private fieldsĪs you know that you can not directly access the private fields declared in a class. I represent some of the use cases you can play with the java objects using reflection. You can refer to any book on java or you can go to Sun site to get large tutorials on reflection. However I am going to give you the details of reflection.
Sometime it is often asked in the technical interview that why it is required or what is the use although we can directly access the class object. Using reflection you can dynamically load the class. The syntax takes the forma as Class.forName( ). You can create an instance of a class using package of JDK. One way you can create an object directly using new operator of the class which is at your classpath. There are two ways you create an instance of a class. As you know reflection is the ability of the software to analyse itself.
JAVA REFLECTION LOAD CLASS HOW TO
In this article I will show you how to break some of the object oriented concept using reflection. It is just a tweak you can make to a java object through reflection. Actually speaking there is no concept of hacking.
This article gives you the inner power of reflection.
