Hello,

Ok so im getting ready to take my final for my java course this Friday and I'm studying my review.

Here what the assignment says:

• You are to highlight inYELLOWall polymorphic variable.
• You are to highlight inGREENall polymorphic methods.
• You are to highlight inBLUEall polymorphic method calls.

In the fellowing code, I did place the letter aside on right the mean the color I would highlight my answer.

I will use Y for Yellow, B for Blue , and G green.

I just someone took look over this code with letter aside and see if I got it write or wrong.

Please correct me if i get it wrong or if I'm missing something.

Thank you so much.
