I’m finding it incredibly difficult to comprehend how different objects should communicate and exchange information.

Coming from the C/C++ world, I’m used to pass objects by reference when I need to give an object to a class/function for processing.

I’m certain that there’s a we’ll known pattern for achieving clean and maintainable way for object communication. I just need to find out what it is.

EDIT: Example

ObjectThatNeedsProcessing obj;
WizardDialog dialog = new WizardDialog;
dialog.addObjectToBeProcessed(obj);
dialog.show();

//When the dialog is finished obj would be changed.

Best regards

    When you pass an object to a method in java, another reference is made to the existing object.
    So you have 2 references to the same object.
