Answer:
Both (i) and (ii) are valid in Java
Explanation:
In (i) 'area' is a variable property of the object myCircle. It could be assigned a value. In this case it has been assigned a value equal to the product of 3.14 and the square of the read input of type double from the keyboard.
After assigning a value to area, it could be printed directly to the console using the println method.
In (ii) 'area' is a method property of the object myCircle. It could be called when the value of the radius(r) has been set using a second method 'set' of myCircle. The call to myCircle.area() probably prints the area of the circle, myCircle, to the console.
In summary, though different, both are valid ways of doing the same thing.
Hope this helps!

Arguably, there wasn't any publishing before movable type and printing presses.
