Last reply by Gevater_Tod4711, over 12 years ago:

I think it would be easyer to compile the .jar file into an .exe file. There it's simple to add an icon. I like the program JMadX. It's very simple but it works.

If you want only one counter (Points) in the vsa class that all its subclasses share, you can use the 'static' keyword in the field declaration in the vsa class: <Code Omitted>My only concern is: why do you have a class and two subclasses for something that can be done in one single class; as only one has an image.

it works now. Thanks!

cannot find symbol

By super_noob, with 6 replies.
Last reply by danpost, over 12 years ago:

Insert at line 3 of the code provided above the following line: <Code Omitted>By declaring a field within a class but outside any method like this, you are giving each instance created by that class a seperate field with that name to use. Of course, if you only create one instance of the class, there will only be one field with that name; but, it belongs to that object created (not to the class itself). EDIT: your welcome.

The keyworld 'this' refers to an Object class object , so that would be one way to use it (if you want it to check for clicks on the current object whose method is being executed on).

By the way, my system would not let me delete some of the files in your scenario (telling me that they were still in use; even when nothing was open). I had to re-format to get rid of them. Fortunately, I am using USB drives. I copied all the files to another flash to re-format, then copied them back. Then, I was able to delete them.

Getting a position of different Objects

By Diphthong, with 4 replies.
Last reply by danpost, over 12 years ago:

Is it a static or non-static variable (non-static will not have the 'static' keyword in its declaration)? If non-static, how many objects of class2 are created and in the world? If only one, then in class1 (and I will give the variable an 'int' type, since you did not say): <Code Omitted>where you have the following method in class2: <Code Omitted>
