JAVA - Data Types and Variables

1. Data Type - int

•   The integer data type is used to store numeric/numbers in the variable. 
•    But a decimal number can not be stored in the 'int' data type.

Example :

 package selenium;

 public class Java_practise {

 public static void main(String[] args) {

                int mark;

mark = 445;

System.out.println("suriya total mark in 10 th " + mark);

 }

 }

2. Data Type - char

•   The character data type is used to store just one character in the variable. It is very rarely used in Selenium. 

Example :

 package selenium;

 public class Java_practise {

 public static void main(String[] args) {

char a;

                 a = 'S';

        //Print the value of the char variable

      System.out.println("Value of char is : " +  a);

}

}

3. Data Type - double

•   To declare a variable used to hold such a decimal number, you can use the double keyword.

Example :

package selenium;

public class Java_practise {

public static void main(String[] args) {

double PI;

    //Initialize the double variable with value 'P'

        PI = 3.14159;

  //Print the value of the double variable

        System.out.print("PI: " + PI);

}

}

Selenium - Get the Actual Message in WebDriver

 Path - 1 :
  WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(3));
      wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("div.alert-danger p")));
      List<String> alertTextList = driver.findElements(By.cssSelector("div.alert-danger p"))
              .stream()
              .map(WebElement::getText)
              .toList();
      System.out.println("Application Status :" + alertTextList);

Path - 2 :
 WebElement actmessage = new WebDriverWait(driver, 15)
           .until(ExpectedConditions.elementToBeClickable(By.className("Toastify")));
 String act = actmessage.getText();
System.out.println("Application Status :" + act);

Path - 3 :
WebElement display =  driver.findElement(By.className("alert-content"));
String act = display.getText();
//To print the value
System.out.println("Element displayed is :" + act);
