Java 验证循环不纠正最后一个错误

Question

这是我正在开发的屏幕：问题如下：如果输入错误，我会得到错误字段的所有错误。但是，对于最后一个字段，它一直告诉我需要输入一个有效字段（即使它已更正）。它只对最后一个字段执行此操作。有谁知道我的问题出在哪里？

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();
                    } else{
                        correct = false;
                        ErrorMessage = 1;
                    }

                    //Check if the field of the first name (admin) is empty, if it is empty, generate an error message
                    if(userDetail.getFirstName().getText().length() != 0){
                        this.firstName = userDetail.getFirstName().getText();
                    } else{
                        correct = false;

            }

例如：输入除 phone 和电子邮件以外的所有字段：它给出了错误的电子邮件通知（我输入了一个好的）。

它给出了一个错误的phone号码通知（我输入了一个正确的号码）。 -> 它一直说我需要输入一个有效的 phonenumber

Answer 1

"last"，我假设你的意思是 "Country"。根据你最后的评论，这些似乎是在别处初始化的，并且在调用 actionPerformed() 后没有被清除，所以在下一次调用时，它们与上一次调用相同，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;

在 actionPerformed() 的顶部
