如何制作自定义例外以指定JTEXTFIELD的特定密码？

Question

我正在尝试在我的解决方案上使用自定义异常，而当“ iammanager”以外的用户输入时，会有一个错误消息。但是，当我尝试运行代码时，有一个错误说“异常永远不会在相应的尝试语句的正文中抛出”。这是我的自定义异常类的代码。

public class InvalidCodeException extends Exception{
    
     //InvalidCodeException(String message){
    //    super(message);
    //}
     
    String managerN ="iammanager";
  
    public InvalidCodeException(String conditionViolated)
    {
        super("Invalid Password: ");
        managerN = conditionViolated;
    }
    
    public String printMessage()
    {
        // Call constructor of parent Exception
        // according to the condition violated
        switch (managerN) {
  
       // Password should not contain any space
        case "one":
            return ("Password should not contain any space");
  
        
        // Password should contain at least
        // one special character ( @, #, %, &, !, $ )
        case "two":
            return ("Password should not contain any special characters");
  
        // Password should not contain any numbers
        case "three":
            return ("Password should not contain any number");
  
        // Password should contain at least
        // one special character ( @, #, %, &, !, $ )
       // case "four":
        //    return ("You do not have access!");
  
        }
  
        return ("You do not have access!");
    }
}

这是我在jform类上的代码当用户输入jtextfield上的名称并按下按钮时，如果用户输入“ iammanager”以外的其他

public static void isValid(String managerN)
       throws InvalidCodeException
    {
  
  
        // to check space
        if (password.contains(" ")) {
            throw new InvalidCodeException("one");
        }
        
  
        // for special characters
        if (!(managerN.contains("@") || managerN.contains("#")
              || managerN.contains("!") || managerN.contains("~")
              || managerN.contains("$") || managerN.contains("%")
              || managerN.contains("^") || managerN.contains("&")
              || managerN.contains("*") || managerN.contains("(")
              || managerN.contains(")") || managerN.contains("-")
              || managerN.contains("+") || managerN.contains("/")
              || managerN.contains(":") || managerN.contains(".")
              || managerN.contains(", ") || managerN.contains("<")
              || managerN.contains(">") || managerN.contains("?")
              || managerN.contains("|"))) {
            throw new InvalidCodeException("two");
        }
  
  
        // for numbers
        if (!(managerN.contains("0") || managerN.contains("1")
              || managerN.contains("2") || managerN.contains("3")
              || managerN.contains("4") || managerN.contains("5")
              || managerN.contains("6") || managerN.contains("7")
              || managerN.contains("8") || managerN.contains("9"))) {
            throw new InvalidCodeException("three");
        }}

  private void confirmActionPerformed(java.awt.event.ActionEvent evt) {                                        
        // TODO add your handling code here:
        
        String managerN = "iammanager";
        
        try {
            managerN = managerName.getText();
            JOptionPane.showMessageDialog(null, "Welcome to User List Manager!" );
        }
        catch(InvalidCodeException e) {
            JOptionPane.showMessageDialog(null, e.getMessage() );
            JOptionPane.showMessageDialog(null, e.printMessage() );
        }
    }        

                           

更新的用户输入尝试catch语句：

private void confirmActionPerformed（java.ava.awt.event.actionevent.actionevent evt）{

// TODO在此处添加您的处理代码：

    String managerN = "iammanager" ;
    
    try {
        
        isValid(managerN);
        managerName.getText().equals("iammanager");
        JOptionPane.showMessageDialog(this, "Welcome to User List Manager !"); 
        //calling user list page
        UserList userP = new UserList();
        userP.show();
        dispose();
        
    }
    catch(InvalidCodeException e) {
        
        JOptionPane.showMessageDialog(this, "You do not have access");
       
        }
    
}                                  

当我使用它时，尝试捕获的错误消息消失了。但是，输出不是我想要的，该代码的输出是它仍然打印了yo，即使我放置了正确的值，即“ iammanager”。谁能告诉我我做错了哪一部分？
