![]() The final class diagram for the Circle class is as follows: Ex: Yet Another Circle ClassĪ class called Circle, which models a circle with a radius, is designed as shown in the following class diagram. ("Operator '+' invokes toString() too: " + c6) // '+' invokes toString() too (c6) // println() calls toString() implicitly, same as above (c5.toString()) // explicit call toString() is called implicitly when an instance is passed to println() method, for example, Try calling toString() method explicitly, just like any other method: ** Return a self-descriptive string of this instance in the form of Circle */ For example, include the following toString() methods to the Circle class: If an instance is passed to the println( anInstance) method, the toString() method of that instance will be invoked implicitly. The toString() method can be called explicitly (via instanceName.toString()) just like any other method or implicitly through println(). ![]()
