我目前正在开发一个程序来解析 CSV,然后根据 CSV 检查输入的电子邮件地址,如果它有效,则显示他们的人员信息。我遇到的问题是 else 声明说您的电子邮件无效。我当前的代码;
import java.io.*;
import java.util.*;
public class CSVReader123{
public static void main(String[] arg) throws Exception {
BufferedReader CSVFile = new BufferedReader(new FileReader("testa453.csv"));
String dataRow = CSVFile.readLine();
//String email = "ojones@coldmail.net";
//String password = "ocrabc";
Scanner input = new Scanner(System.in);
System.out.println("Please input an email adress");
String email = input.nextLine();
System.out.println("Please input you password");
String password = input.nextLine();
while (dataRow != null){
String[] dataArray = dataRow.split(",");
if ((dataArray[0].equals(email)) && (dataArray[1].equals(password))) {
System.out.println("Your email is valid");
System.out.println("Do you want to display you personel data?(Y or N)");
String personeldata = input.nextLine();
if ((personeldata.equals("yes")) || (personeldata.equals("Yes")) || (personeldata.equals("Y"))){
System.out.println("You email is " +dataArray[0]+".");
System.out.println("You password is " +dataArray[1]+".");
System.out.println("You first name is " +dataArray[2]+".");
System.out.println("You second name is " +dataArray[3]+".");
System.out.println("You street name is " +dataArray[4]+".");
System.out.println("You city name is " +dataArray[5]+".");
System.out.println("You postcode is " +dataArray[6]+".");
}
else if ((personeldata.equals("no")) || (personeldata.equals("No")) || (personeldata.equals("N"))) {
System.out.println("Shutting down.");
break;
}
}
else {
System.out.println("BROKEN");
break;
}
System.out.println();
dataRow = CSVFile.readLine();
}
CSVFile.close();
System.out.println();
}
}
我遇到的问题是,如果我尝试输入有效或无效的电子邮件,它总是会打印出损坏并停止。虽然如果我删除所说的 if 语句,程序运行完美,其余部分正常工作。自从第一个 else 语句完美运行以来,我是否以某种方式在不正确的位置声明了它?任何帮助,将不胜感激。
