Create an interface called Visible that includes two methods: makeVisible and makeInvisible. Both methods should take no parameters and should return a boolean result. Describe how a class might implement this interface.

Question

What will be an ideal response?

Answer 1

```
public interface Visible
{
public boolean makeVisible();
public boolean makeInvisible();
}
```
A class implementing Visible would include an implements clause in the class header, such as:
public class ControlPanel implements Visible
The class would contain, among other things, two methods with signatures that match those specified in the interface.
