無法將參數從一個類方法調用到另一個類方法

Question

我嘗試使用下面的代碼有兩個類，一次是 Class1-TestData 和 Method1-excel()，另一個調用是訪問參數 Class2-AdminLoginAction 和 Method2-Admin_Login()。

這是我需要調用字符串參數（如我在隨附的屏幕截圖中標記的 UID 和 PWD）的問題。 但是腳本顯示了一些錯誤並且無法訪問它。 那么，我該如何解決這個問題，我是采用正確的方法還是采用其他任何方式？ 請盡快完成需要。

兩個類的腳本圖像

public void Admin_Login() throws InterruptedException, IOException {
    TestData excel = new TestData();
    
    extent.attachReporter(spark);
    ExtentTest test = extent.createTest("Launch browswer and access the WeClean Login page");
    test.log(Status.PASS, "Launch browser success...!!!");

     XSSFCell cell=row2.getCell(0);
     double UID= cell.getNumericCellValue();
     XSSFCell cell2 = row2.getCell(1);
     String PWD = cell2.getStringCellValue();
    }

Answer 1

你可以這樣嘗試：

public class TestData {
    double UID;
    String PWD;
    
    public void excel() throws IOException {
        String filePath = System.getProperty("user.dir") + "\\Inputfiles";
        File file = new File(filePath + "\\TestData.xlsx");
        FileInputStream inputStream = new FileInputStream(file);
        XSSFWorkbook wb = new XSSFWorkbook(inputStream);
        XSSFSheet sheet = wb.getSheet("Admin_inputs");
        XSSFRow row2 = sheet.getRow(1);
        XSSFCell cell = row2.getCell(0);
        UID = cell.getNumericCellValue();
        XSSFCell cell2 = row2.getCell(1);
        PWD = cell2.getStringCellValue();
    }
}

在Admin_Login()方法中，我只是打印UID和PWD ，根據您的要求更改代碼：

public class AdminLoginAction extends TestData {
    @Test()
    public void Admin_Login() throws InterruptedException, IOException {
        // TestData excel = new TestData();  // you don't need to create this object because you are already inheriting `TestData` class.

        excel();  // before using UID and PWD you have to call excel() method.
        System.out.println(UID);
        System.out.println(PWD);
    }
}
