class Rectangle extends Figure
{
void display( )
{
System.out.println("Rectangle");
}
}
class Box extends Figure
{
void display( )
{
System.out.println("Box");
}
}
Inherit( )
{
Figure f = new Figure( );
Rectangle r = new Rectangle( );
Box b = new Box( );
f.display( );
f = r;
f.display( );
f = b;
f.display( );
}
public static void main(String[ ] args)

d) Syntax error; this code won't compile or execute

Answer 1

The code provided creates instances of nested classes and calls their respective display methods to print specific messages.

Step-by-step explanation:

The code provided defines a class Inherit with three nested classes: Figure, Rectangle, and Box. Each class contains a method called display() that prints out a specific message.

In the main method, an instance of each class is created: f represents a Figure, r represents a Rectangle, and b represents a Box. The display() method is called on each instance, resulting in the output: Figure, Rectangle, and Box.

The correct answer is Option (a) FigureRectangleBox.
