sou iniciante em java
ta fazendo um gerador de codigos pra java
entao
to com um problema
ai no programa tem um fundo preto
eh um textarea
dai abro um janela pra criar as classes
dai quando clico em criar classe mando dar um append no textarea com o
nome da mesma
soh q ele nao faz isso
n aparece nada
o q poderia ser
em anexo vai o codigo
valeu e ate mais
