*** Please don't use handwriting **** I need unique answer

Q1:

Write a java program that make use of the following interfaces and classes to display the steps one should follow to prepare tea, coffee, and warm milk.

Classes:

1- A class called Tea to prepare tea.

2- A class called Coffee to prepare coffee.

3- A class called WarmMilk to prepare warm milk.

Interfaces:

  1. Pot has void FillPot(); method signature.
  2. Stove has void PutOnStove(); method signature.
  3. Cup has void PourIntoCup();method signature.
  4. Boil has void BoilPot(); method signature.
  5. HeatWithoutBoil has void JustHeat(); method signature.

To prepare tea or coffee, one should make sure that cold water and tea or coffee is mixed into the pot, boiled, and then it should be poured in cup.

To prepare warm milk, one should pour cold milk into a pot, heat the milk without reaching its boiling point. Then, pour the milk in a cup.

Make sure that you only use the interfaces that are appropriate for each class. For example, the Tea class will only implement pot, stove, cup, boil interfaces.

Q2:

When formal development processes were first established in the early 1970s, software engineers had a very simple visual model of these phases. They assumed that one phase would run to completion, its output would spill over to the next phase, and the next phase would begin. This model is called the waterfall model of software development. In your own words, write any five disadvantages of using this model.

Pour the tea from the pot into the cup and enjoy your drink. -To prepare coffee, use the following steps: Fill up the pot with cold water and Coffee. Place the pot on top of the stove. Bring the pot to boil. Pour the coffee from the pot into the cup and enjoy your drink -To prepare warm milk, use the following steps: Fill up the pot with cold milk. Place the pot on top of the stove. Heat the pot without reaching the boiling point. Pour the warm milk from the pot into the cup and enjoy your drink
