1. Dummy GUI Application by Codechum Admin A GUI Application is an application that has a user interface that the user can interact with. For this program, we will be simulating this behavior. First, implement another class called Checkbox which implements the Clickable interface which has only one method: public void click(). The Checkbox will have the following properties: private boolean isChecked (defaults to false upon the creation of object) private String text Additionally, it should have the following methods: the implementation of the click() method If the isChecked is currently false, this will set the isChecked to true and will then print the message "Checkbox is checked". If it is currently true, this will set the isChecked to false and will then print the message "Checkbox is unchecked". Note that the messages to be printed should have also print a new line at the end. an override of the toString() method which returns the message: "Checkbox ({text} - Clicked…
