Se você quer ajuda, nos ajude.

Em primeiro lugar, ponha o seu código entre as tags code, como descrito aqui:
http://www.guj.com.br/posts/list/50115.java

Em segundo, ponha a mensagem de erro que o netbeans está dando, se possível destacando a linha do erro com algum comentário.

Ah sim… e evite “mendigar ajuda” ou “gritar por socorro” no forum.
