can some one please tell me whats the different of readable and writable properties.
Readable properties are properties you can read, usually via a getter method. And writable properties are properties whose value you can change, usually via a setter method.
Also if we write a bean class we have to also declare the properties know..having set get methods is not enought right?
Don't forget that you're still using
Java. You need to declare the properties, otherwise how would you compile it ? You could use something else, like a Map, to store them. In any case, you would still need something to store them.
