    Default Running one of the Oracle tutorials

    I'm going through the Oracle tutorials at the moment and this one is just throwing up load's of error's in Eclipse.

    It's the objects tutorial and it's in three parts, I copy pasted the code into different classes in Eclipse, but there're lot's of errors.


    here's the program (you need all three of these:

    CreateObjectDemo

    Point

    Rectangle



    I was just wondering if anyone else got these errors when they tried them on their computers? I must be doing something wrong on the initial import stage, I'm not sure what though

    Hi, the three classes are working fine for me, being all in one package. Make sure youre not referencing the java.awt.Point and Rectangle classes. This is one of the bad examples in the Oracle tutorials. Your own classes should never have the same name as a class in the JDK. Just rename Point to MyPoint and Rectangle to MyRectangle and change the references in CreateObjectDemo.

    Ah cheers PhHein! Yeah that's amazingly poor for a tutorial, there's been a couple of occasion's going through the tutorial that they seem to have done something in a particularly bad way...

    Program's up and running now, nice one

    I'm glad it works. I've just filed an issue with Oracle about reusing class names in the tutorails We'll see what the reply is.
