Freezing and Boiling Points
The following table lists the freezing and boiling points of several substances.
| Substance | Freezing Point | Boiling Point |
| Ethyl Alcohol | −173 | 172 |
| Oxygen | −362 | −306 |
| Water | 32 | 212 |
Design a class that stores a temperature in a temperature field and has the appropriate accessor and mutator methods for the field. In addition to appropriate constructors, the class should have the following methods:
- isEthylFreezing. This method should return the boolean value true if the temperature stored in the temperature field is at or below the freezing point of ethyl alcohol. Otherwise, the method should return false.
- isEthylBoiling. This method should return the boolean value t rue if the temperature stored in the temperature field is at or above the boiling point of ethyl alcohol. Otherwise, the method should return false.
- isOxygenFreezing. This method should return the boolean value true if the temperature stored in the temperature field is at or below the freezing point of oxygen. Otherwise, the method should return false.
- isOxygenBoiling. This method should return the boolean value true if the temperature stored in the temperature field is at or above the boiling point of oxygen. Otherwise, the method should return false.
- isWaterFreezing. This method should return the boolean value true if the temperature stored in the temperature field is at or below the freezing point of water. Otherwise, the method should return false.
- isWaterBoiling. This method should return the boolean value true if the temperature stored in the temperature field is at or above the boiling point of water. Otherwise, the method should return false.

Cargo Ships
This question involves cargo ships that carry a specific number of cargo containers. Each ship has a maximum number of cargo containers that it can hold and a current number of cargo containers that it is holding. You can see more details in the Ship class that is provided for you.
Part A
For part A, you will be completing the nextToUnload() method. This takes no input and returns a Ship from the ships instance variable that has the highest percentage of its cargo hold filled (as measured by current hold / capacity). If two ships have the same percentage, then it should return the first ship with that percentage.
If all of the ships in the ships array are empty (ie. no cargo), the method should return null.
Part B
For part B, you will complete the two unloadShip methods. The first method takes a Ship object and unloads all of the cargo from that ship. The second method takes a Ship and an int and unloads the specified number of containers from the ship. If the number of…
