所以，最近，我父亲让我做一个涉及收集用户名、密码等的项目，这样他就可以有一个固定的位置来找到他所有的登录信息。
我有一个程序可以在每次运行程序时成功收集信息并写入一个新的文本文件。我的目标是使信息存储在 SAME 文件中，但每组信息之间有一个空格。
这是我的代码（对不起，我只有 14 岁）：
package com.src.java;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.MalformedURLException;
import javax.swing.JOptionPane;
import javax.swing.JTextField;
import javax.swing.UIManager;
public class Info {
public static void main(String args[]) throws MalformedURLException,
IOException, InterruptedException {
boolean run = true;
while (run) {
JTextField companyName = new JTextField();
JTextField userName = new JTextField();
JTextField password = new JTextField();
JTextField accountNumber = new JTextField();
JTextField phoneNumber = new JTextField();
JTextField address = new JTextField();
UIManager.put("OptionPane.cancelButtonText", "Exit");
UIManager.put("OptionPane.okButtonText", "Create File");
Object[] message = { "Company name: ", companyName, "Username:",
userName, "Password:", password, "Account number:",
accountNumber, "Phone number:", phoneNumber, "Address:",
address, };
int option = JOptionPane.showConfirmDialog(null, message,
"Fill out your info...", JOptionPane.OK_CANCEL_OPTION);
if (option == JOptionPane.OK_OPTION) {
String cN = companyName.getText();
String uN = userName.getText();
String pw = password.getText();
String aN = accountNumber.getText();
String pN = phoneNumber.getText();
String ad = address.getText();
PrintWriter writer = new PrintWriter(cN + ".txt", "UTF-8");
writer.println("Company name: " + cN);
writer.println("User name: " + uN);
writer.println("Password: " + pw);
writer.println("Account number: " + aN);
writer.println("Phone number: " + pN);
writer.println("Address " + ad);
writer.close();
System.out.println("Wrote file: " + cN + ".txt");
Thread.sleep(500);
} else {
System.exit(0);
}
}
}
}
