每当我尝试单击该按钮时，它都会提示我找不到用户名，但是每当我尝试输入从哈希图中输入的人口时，它都会引导我打印我输入的信息。我认为我的哈希图不是不会被覆盖。这是我的 ID、名字、姓氏和密码的哈希图代码。

在我的登录页面

您在类
IDandPasswordsWelcomePageIDandPasswords idAndPasswords = new IDandPasswords();
您在
IDandPasswordsLogIn PageLogIn PageloginInfo.put(userID, new IDandPasswords.UserInfo(firstName, lastName, password));
我还假设
loginInfoIDandPasswords因此，类
idAndPasswordsWelcomePageloginInfoidAndPasswordsloginInfo您需要将
loginInfoWelcomePageWelcomePageLogIn PageWelcomePageWelcomePage(String userID, IDandPasswords idAndPasswords) {
this.idAndPasswords = idAndPasswords;
}
或者，可以将类
IDandPasswordslogininfoimport java.util.HashMap;
import java.util.Map;
public class IDandPasswords {
private static Map<String, UserInfo> logininfo = new HashMap<>();
static {
// Populate logininfo
logininfo.put("Justine", new UserInfo("Cute", "Realubit", "pizza"));
logininfo.put("Kacey", new UserInfo("Cute", "Gutierrez", "PASSWORD"));
logininfo.put("Joshua", new UserInfo("Cute", "Santos", "abc123"));
}
public static boolean isValidUserId(String userId) {
return logininfo.containsKey(userId);
}
// Method to update user information
public static void updateUserInfo(String userId,
String newFirstName,
String newLastName,
String newPassword) {
UserInfo user = logininfo.get(userId);
if (user != null) {
user.setFirstName(newFirstName);
user.setLastName(newLastName);
user.setPassword(newPassword);
} else {
System.out.println("User not found!");
}
}
public static Map<String, UserInfo> getLoginInfo() {
return logininfo;
}
public static class UserInfo {
private String firstName;
private String lastName;
private String password;
public UserInfo(String firstName, String lastName, String password) {
this.firstName = firstName;
this.lastName = lastName;
this.password = password;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
}
那么您将始终访问和修改同一个
