U The "Tool" class has a constructor Tool(int) used to initialize the "length" in inches of any tool. The "Hammer" class is a subclass of "Tool". It has an instance variable of type double named "power" that indicates the amount of hitting force that the hammer can generate. Give UML diagram of Tool and Hammer. Write the class of Tool and Hammer. Be sure to implement the Hammer constructor that initializes the Hammer's "length" and "power". Be sure to make use of the Tool(int) constructor. Also, write the Hammer class method display() that prints the Hammer's power and then invokes the overridden Tool method display to print the rest of the information about the Hammer.
