Java验证循环不能纠正最后一个错误
这是我正在开发的屏幕：
问题如下：
如果输入错误的输入，我会得到错误字段的所有错误。然而，对于最后一个字段，它一直告诉我我需要输入一个有效的字段（即使它被纠正）。它只对最后一个字段执行此操作。有谁知道我的问题所在？
这是我的代码：
public void actionPerformed(ActionEvent e) {
try{
//Check if the field of the enterprise name is empty, if it is empty, generate an error message
if(enterpriseGeneral.getEnterpriseName().getText().length() != 0){
this.entName = enterpriseGeneral.getEnterpriseName().getText();

答案 0 :(得分：1)
通过＆＃34; last＆＃34;，我假设你的意思是＆＃34;国家＆＃34;。基于你的上一条评论，似乎这些在其他地方被初始化，并且在调用actionPerformed（）之后没有被清除，所以在下次调用时，它们与之前的调用相同，如果没有错，它们仍然有错误值从以前的电话。你可能想做一个
correct = true;
位于actionPerformed（）
的顶部
