Why i can't open the new main of this cheak win?

Why i can't open the new main of this cheak win?

I don't understand your question, please rephrase it. btw, your code is overly
repetative and not very well organized.

kind regards,

Jos

ps. I added those [ code ] ... [ /code ] tags for you.

For this, plx tell me why the NeilClass does not exit?

[JosAH]

For this, plx tell me why the NeilClass does not exit?

I don't know why that class doesn't exist. Maybe you haven't compiled it or
maybe it can't be found in the classpath list. Please don't dump all your code
here without those [ code ] tags. Read the instructions in the 'help' link before
you post here. (see the top of this page)

Also read the "Read This First" article near the top of this page for useful links.

kind regards,

Jos
