JAVA way to count how many getters in bean that are not null

Ok I have a bean list and I can do `beans.size()` to get how many rows I got.....but I need to dynamically know how many columns of data I have before I send to the jsp. The maximum # of getters I have in the bean is 10.... Is there a way to do this?? Would I have to do a loop on the list and do a `If` check on all the getters and increment?

以上就是JAVA way to count how many getters in bean that are not null的详细内容,更多请关注web前端其它相关文章!
