CST 112 -- Specifications for Project #7

Declare a class named "Person"¹ containing the following data variables (with types as indicated).

id (int): A unique number to identify this person, (You may use the array index for this.)
gender (boolean): Use true for male, false for female.
name (String): name of this person
height (Float): height of this person (in inches)
bmi (Float): BMI index (see below)
born (int): The year this person was born (between 1920 and 2000).
NOTE: You may create additional variables and methods, as necessary.

Write a 7-argument constructor method, to set all data variables.
Also write a constructor with only the first three arguments (id, gender, and name), that randomly fills the other data variables (except bmi) as follows

For year of birth, use a random number between 1920 and 2000.
For height, use a random number between 60 and 76 for males, or between 56 and 72 for females.
For weight, choose a random number from 120 to 200 for males, or from 100 to 180 for females.

Also recalculate the BMI.

Add a method named "show()" to display the data, as shown in the example.
Add a method named "showLabels()" to display labels for each column (as shown).

Add a method named bmiCalc()to re-calculate the "BMI" (Body-Mass Index)

			//// Calculate bmi index. ////
  			/*
			  Formula: weight (lb) / [height (in)]2 x 703
			  Calculate BMI by dividing weight in pounds (lbs) 
			  by height in inches (in) squared 
			  and multiplying by a conversion factor of 703.
			*/

Add a method named "nextYear()" to update the data for the next year.
++++ Details will be supplied later +++

    //// Grow taller:  +1 when under 18, up to 1/2 thereafter, then shrink up to 1/10 after 50
    //// Gain up to 5 when under 18y, then random +/10 per year (avg +1).

Declare a "global" array of 20 "Person" objects.
Write a method to fill the array with People objects with gender and name input from a file. (See the starting code at "project7.java"), and use the above three-argument constructor to create random values.
The "number" variable" should be set equal to the array index plus 1 (i.e. 1 to 20).

Respond to keys, as described in the sample (or in the "help" method). These include:

		  KEYS:
		  f:  Fill the people array  with new values
		  a:  Sort by age
		  h:  Sort by height
		  w:  Sort by weight
		  b:  Sort by BMI
		  q:  Quit
		  y:  NEXT YEAR
