以下程序执行后,修改的记录全变为0,不知为什么?

if (!aenglish.equals("")) {
int english = Integer.parseInt(aenglish);
atotal = atotal + english;
rs.updateInt("english", english);
rs.updateRow();

C'mon, it is a very easy program to debug with. Or simply print the value of "english" to your trace log before updating the database. I don't see any difficulty of doing this.

You shall fix it yourself.

我想是equals()方法没有重写吧...
equals()默认对比的是引用
