Are you using any framework like cairngom or something?
Try to debug from flex to java..

properties used by drool engine such as compiler etc
configurations..

What is location and example of properties file used in drools?

Where are the generated rule class files are stored as java files when used eclipse?

What is mean by AST and descr in drools 4?

why one can not import classes from default package in java?

You probably referencing to different objects.

Declaring static fields in any class means those varibles can be accessed without instatiating object of that class.
Example
Class MyClass{

static declaration including objects or array or primitive..
}

Static varible does not mean that you do not instantiate it.It means you do not require to instatiate the class in which they are declared however you need to create a object of that whether that variable is declared static or not...

Do you require more clarification?
or you got it?

Thanks Mike,Manish and Ulf ..

Then someonce use varibale instead of constant if they want to change its value.
anyway if it is constant then its value may be considered as unchanged.

Hi,
I would like to share few places where behavior of program is different than expected.
I would be glad if someone can clarify it.
Case 1:
scenario A:
consider the following code

while(false){

System.out.println("It wont be executed");
}


Scenario B:-
if(false){
System.out.println("It wont be executed either");
}

Situation:- in both the cases condition is defined at runtime. It means compiler knows that none of the print statement ever executed.
However in scenario A it gives it as unreachable code which is quite expected but in case of scenario B it runs just fine which is not expected.
Do somebody has any thought on this?
And one more thing do not descibe what is unreachable code and how while and if works. i knew that already....

Thanks

I am not interesed in thease keywords are used as methods.
My view is second case where these are treated as references.

If there is refrence either it is null or referencing not null object

we can define same variable both in parent and child class

if we directly used the variable in child class it refers the child class version and when we use super.variable_name it looks for varible of parent although it is overriden

In fact if we do not create a same variable name we can use "this" to refer a varible from parent class provided that it is not private

This means along with the inherited properties and methods in child class some of the things are not accessible using "this" thats why we need super, is it so?
And there is no object other than child class is created
one more thing two object of type Class are created
This is what is my understanding
please correct me if I m wrong

As Per My understanding

this---> refrence to current class's object
and
super--> reference to parent class

Q1. are the above statements are true?
if no
how can you access any method or variable without using refrence?
if yes
then what is refrenced by super?

Do you mean that it is not a reference?

I know what is meant by this
My question was what Super represents if superclass object is not created?
