checkbox selenium code example

Example 1: checkbox and radio button in selenium

- I locate it as just another web element AND CLICK.
    - I would verify if checkbox is selected or not by
        - .isSelected() method will return true if checkbox is selected.
        - .isSelected() method will return false if checkbox is NOT selected.
syntax: checkbox.click();
syntax: checkbox.isSelected(); --> will return boolean: true/false

isSelected() isSelected()--> true,  else --> false 
This method checks if the checkbox/radiobutton is selected or not selected. 
isEnabled() isEnabled -> true,  else --> false
This method checks if the checkbox/radiobutton is enabled to be clicked.      
isDispalyed()  isDispalyed()-> true, else --> false
