Answer and Explanation:
The output is false because Circle is used. Circle class has two methods, such as ( Circle circle ) and Object o that defined in the Object class. The Circle class inherits it. Circle.euqlais equaled to Object o because it is the type of circle1 and circle 2. The object of Circle is match circle1. equal by the compiler.
The output is accurate if Circle class overrides the equals to defined in Object class. The circle is matched to equals to object and run time method implemented in Circle class.
Both Circle has a different address. With Circle.equals(circle 2) replaced and have a same method in Object class.
Yes the following statement can be compiled the Circle circle = new Circle(5);
Geometric Object object = circle;
In this Object o is used to compile and run time as the circle has a different address. Method overriding allows dynamic binding, but it is always determined by declared type.
You should probably slow down, make sure no trains are coming (and listen for any train sounds!) before proceeding to cross and go about your way :)
