## V22.0002 - ASSIGNMENT 2

An integral part of scuba safety is the management of the nitrogen levels in your body. If you
have too much nitrogen in your body, you can get the bends. Todays scuba divers use charts and
computers to determine how long they can be submerged at a particular depth.
For this assignment, you are to write a program to compute the maximum bottom time for a sport diver
based on a few variables. NOTE: This is an oversimplified example for this class and will not compute
safe bottom times.

__Your program should ask the user for:__

The desired depth of the next dive
The number of previous dives during the day
Then it must calculate the maximum time permitted at the desired depth. For this assignment,
we will assume a sport diver does not dive below 60 feet. Furthermore, we assume a diver will
not participate in more than 5 dives in one day.

Following is a table you can use to calculate the bottom time without regard
to the number of previous dives:

**Desired Depth** |
**Maximum Bottom Time (without Secondary Dive Penalty)** |

1 - 20 feet |
90 minutes minus 75% of the maximum depth |

21 - 30 feet |
75 minutes minus 80% of the depth exceeding 20 feet |

31 - 40 feet |
68 minutes minus 100% of the depth exceeding 30 feet |

41 - 50 feet |
58 minutes minus 120% of the depth exceeding 40 feet |

51 - 60 feet |
44 minutes minus 150% of the depth exceeding 50 feet |

The Secondary Dive Penalty is an amount deducted from your maximum bottom
time due to the nitrogen contained in your blood from previous dives:

**Number of previous dives** |
**Penalty** |

0 |
0 minutes |

1 |
4 minutes |

2 |
10 minutes |

3 |
17 minutes |

4 |
27 minutes |

__It should then output the following:__

Maximum Depth
Bottom time without the Secondary Dive Penalty
Secondary Dive Penalty
Maximum Bottom Time
Example:

Enter the maximum depth of your next dive in feet: 44

Enter the number of dives you have completed already today: 2

44 |
Feet Maximum Depth |

53.20 |
Bottom time without the Secondary Dive Penalty |

10.00 |
Secondary Dive Penalty |

43.20 |
Maximum Bottom Time |

You should read integer values from the user (ie. Use JOptionPane to get a string and then use Integer.parseInt() to convert that string to an integer). When you output the times, you can either:

Output your times as float values as shown above (ie. three and one half
minutes would look like this 3.50)

break the fractional portion of your minutes into its equivalent in
seconds. (ie. three and one half minutes would look like this 3:30)
In either case, alignment of the output values is important.

You must use **if** / **else if** / **else** statements to choose
between the formulae for calculating the Bottom Time without the Secondary Dive
Penalty. (Even if you can figure out the single formula to calculate the bottom
time for any depth.)

You should use a **switch** statement to determine the Secondary Dive
Penalty.
