How to check if the radio button is selected or not in Selenium WebDriver?

Question

Here is my HTML code

Answer 1

driver.findElement(By.id("26110162")).isSelected();

or

String str = driver.findElement(By.id("26110162")).getAttribute("checked");
if (str.equalsIgnoreCase("true"))
{
    System.out.println("Checkbox selected");
}

if the ID is changing... use the following XPATH:

//input[span='Seleccionar como tarjeta predeterminada']

or

//input[@name='address' and @type='radio']
