How to handle Select in Selenium

Example of using Select in Selenium 

public static void main(String[] args) throws InterruptedException {
WebDriver driver = new FirefoxDriver();
driver.get("https://www.mobikwik.com/");
driver.manage().window().maximize();
driver.findElement(By.xpath("//*[@id='mobile_number']")).sendKeys("9910979218");
driver.findElement(By.xpath("//*[@id='mobile_amount']")).sendKeys("10");
WebElement operator = driver.findElement(By.xpath("//*[@id='mobile_operator']"));
Select option = new Select(operator);
option.selectByVisibleText("Idea");
Thread.sleep(5000);
driver.close();
}

Access Modifiers in Java

We always use Public, Private, Protected in our Selenium scripts. Before using these, we should know how and where to use these access modifiers. Here is the table showing where we can call these modifiers:

Access Modifier	within class	within package	outside package by  subclass only	outside  package
Private	Y	N	N	N
Default	Y	Y	N	N
Protected	Y	Y	Y	N
Public	Y	Y	Y	Y
