JAVA:向方法添加新参数

Question

我有一个方法addNewUser，它要求用户提供用户名、电子邮件和密码。这些将存储在 Excel 工作表的相应列中。请参阅下面的代码:

public class ExcelConfig {



public FileInputStream fis;
public FileOutputStream fos;
public XSSFWorkbook wb;
public XSSFSheet sh;
public XSSFRow row;
public XSSFCell cell;

int lastRow = 0;

ConfigReader cr = new ConfigReader();

public ExcelConfig(){

      try {
        fis = new FileInputStream(cr.getExcelPath());
        wb = new XSSFWorkbook(fis);
       } 
       catch (Exception e) {
        System.out.println("Error at ExcelConfig " + e.getMessage());
       }


}


public void addNewUser(String un, String em, String pw){


      cell = row.createCell(0);
      cell.setCellValue(un);

      cell = row.createCell(1);
      cell.setCellValue(em);

      cell = row.createCell(2);
      cell.setCellValue(pw);


}

}

现在，在其他类中，我调用了 addNewuser 方法。请参阅下面的代码

public class NextStepTest {

WebDriver driver;

ConfigReader cf;
ExcelConfig ec;
UserDetails ud;

LandingPage lp;
RegisterPage rp;

String username;
String email;
String password;




@BeforeTest
public void setUp(){
    cf = new ConfigReader();
    ec = new ExcelConfig();
    ud = new UserDetails();


    driver = cf.getChromeDriver();
    driver.get(cf.getAppUrl());


}

@Test
public void register(){

    username = cf.getUsernameFromProperty();
    email = cf.getEmailFromProperty();
    password = ud.getPassword();

    try{

        lp = new LandingPage(driver);
        lp = PageFactory.initElements(driver, LandingPage.class);

        lp.locateRegisterLink();
        lp.clickRegisterLink();

        rp = new RegisterPage(driver);
        rp = PageFactory.initElements(driver, RegisterPage.class);


        rp.locateUsernameField();
        rp.registerAccount(username, email, password);


        ec.getSheet(0);
        ec.getNextRow();
        ec.addNewUser(username, email, password); // here I call addNewUser method that now has username, email and password values
        ec.closeFile();

        rp.logout();
        lp.locateLoginLink();



    }
    catch(Exception e){
        System.out.println("Error under NextStepTest.java => " + e.getMessage());

    }



}

现在，我想问的是，是否可以使addNewUser方法参数动态化？我知道这种情况取决于项目。某些项目可能只需要用户名、电子邮件和密码(在这种情况下)即可在 Excel 上添加。如果以后的其他项目需要添加账户类型怎么办？因此参数现在将变为 4。或者其他项目只需要电子邮件和密码。我应该每次都更新 addNewUser 方法参数吗？我还是这门语言的初学者。任何帮助都可以。谢谢大家!

Answer 1

What if in the other future project , it will require to add an account type?

那么将来你需要重载该方法

public void addNewUser(String un, String em, String pw){

}

//only username
public void addNewUser(String un){

}

//with all the info + token
public void addNewUser(String un, String em, String pw, String token){

}

您唯一需要注意的是:这些都是字符串...所以您需要预先知道哪个字符串对应哪个参数...
