Java驗證循環無法糾正最后的錯誤

Question

這是我正在開發的屏幕： 問題如下：如果我輸入了錯誤的輸入，我會得到所有錯誤字段的錯誤。 但是，對於最后一個字段，它總是告訴我我需要輸入一個有效的字段（即使已更正）。 它僅對最后一個字段執行此操作。 有誰知道我的問題所在？

這是我的代碼：

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{

                    }
                }


            }

例如：在電話和電子郵件以外的所有字段中輸入：它給出了錯誤的電子郵件通知（我輸入了一個好消息）。

它給出了錯誤的電話號碼通知（我輸入了一個好電話）。 ->一直說我需要輸入一個有效的電話號碼

“最后”是指您的國家。 根據您的最后一條評論，似乎這些變量已在其他地方初始化，並且在調用actionPerformed（）之后未清除，因此在下一次調用時，它們與上一次調用相同，並且如果沒有錯誤，則它們仍具有錯誤值來自先前的通話。 您可能想做一個

correct = true;

在actionPerformed（）的頂部
