Other practice ideas: write a simple object oriented program which asks the user to enter the height of the average human and the height of the tower of Pisa and then computes and prints how many humans high the Tower of Pisa is$.$ Write a flow chart for the main method and the worker method and a test table.

Example computer run:

What is the height of the average human in meters: $1\mathrm{.}5$

What is the height of the tower of pisa: $57$

Then tower of Pisa is $38\mathrm{.}0$ humans high

You must know these terms and how to write them: method, parameter, variable, parameterized constructor, no$-$arg constructor, setters, getters, worker method.$$ You should know how to use printf.
