Java Programming Help?

Question

I Need Help Writing A Program using the following information. I already have the Data file saved on my computer to.
From an article from the Mathematics Teacher, February 1981. Knowing the exact physical dimensions of a victim of a crime is extremely useful in identifying the victim. When a skeleton is found, a forensic scientist uses the lengths of certain bones to calculate the height of the living person. The bones that are used are the femur (F), the tibia (T), the humerus (H), and the Radius (R). When the length of one of these bones is known, one of the following formulas is used to determine the height. All measurements are in centimeters.

Male
h= 69.089 + 2.238 X F
h= 81.688 + 2.392 X T
h = 73.570 + 2.970 X H
h = 80.405 + 3.650 X R

Female
h = 61.412 + 2.317 X F
h = 72.572 + 2.533 X T
h = 64.977 + 3.144 X H
h = 73.502 + 3.876 X R

.After the age of thirty, the height of a person begins to decrease at the rate of approximately 0.06 cm per year. This shrinkage must be considered when the age of the victim is known.

Write a program that will determine the height of a person from provided data. The data will consist of a lead value indicating the number of bones to be analyzed. Data for each bone will consist of the following information:

1. Male or female (F or M)
2. Type of bone (F, T, H, or R)
3. Estimated age of person
4. Length of bone

Sample Output (What It Should Look Like)
sex	bone	age	length	height
F	H	45	36.266	178.097
M	F	18	46.967	174.201
M	H	29	33.309	172.498
M	T	95	36.983	166.251
M	R	30	23.177	165.000
F	F	31	42.550	159.940
F	F	65	39.960	151.899
F	T	50	30.962	149.799
F	R	80	19.375	145.600
M	H	3	624.017	144.540
Q	F	40	30.000	Wrong Sex Code
M	Q	40	30.000	Wrong Bone Code

I would go about doing something like this.  The only thing I didn't do was the "Wrong Sex Code" and "Wrong Bone Code".  I'm thinking of how to do this, since height is a type double, and can't output a String easily.  BTW, what do you do if both the sex and bone type are wrong?

EDIT:  OK I guess this way will work. I added some if else statements for what the height output will be, where heightoutput is a String.  If everything is fine, heightoutput is the height made into a String.

public class Bones {

public String findHeight(char sex, char bone, int age, double length) {
double height = 0;
if (sex == 'M') {
switch (bone) {
case 'F':
height = 69.089 + (2.238 * length);
break;
case 'T':
height = 81.688 + (2.392 * length);
break;
case 'H':
height = 73.570 + (2.970 * length);
break;
case 'R':
height = 80.405 + (3.650 * length);
break;
}
} else if (sex == 'F') {
switch (bone) {
case 'F':
height = 61.412 + (2.317 * length);
break;
case 'T':
height = 72.572 + (2.533 * length);
break;
case 'H':
height = 64.977 + (3.144 * length);
break;
case 'R':
height = 73.502 + (3.876 * length);
break;
}
}
if (age > 30) {
int years = age - 30;
height = height - (years * .06);
}
if((sex != 'M') && (sex != 'F')){
			heightOutput = "Bad Sex Code";
		}
		else if((bone != 'F') && (bone != 'T') && (bone != 'H') && (bone != 'R')){
			heightOutput = "Bad Bone Code";
		}
		else{
			heightOutput = Double.toString(height);
		}
		return sex + "&#92;t" + bone + "&#92;t" + age + "&#92;t" + length + "&#92;t" + heightOutput + "&#92;n";
}

public static void main(String[] args) {
Bones b = new Bones();
System.out.println("sex &#92;t bone &#92;t age &#92;t length &#92;t height");
System.out.println(b.findHeight('F', 'H', 45, 36.266));
System.out.println(b.findHeight('M', 'F', 18, 46.967));
System.out.println(b.findHeight('M', 'H', 29, 33.309));
System.out.println(b.findHeight('M', 'T', 95, 36.983));
System.out.println(b.findHeight('M', 'R', 30, 23.177));
System.out.println(b.findHeight('F', 'F', 31, 42.550));
System.out.println(b.findHeight('F', 'F', 65, 39.960));
System.out.println(b.findHeight('F', 'T', 50, 30.962));
System.out.println(b.findHeight('F', 'R', 80, 19.375));
System.out.println(b.findHeight('M', 'H', 3, 624.017));
System.out.println(b.findHeight('Q', 'F', 40, 30.000));
System.out.println(b.findHeight('M', 'Q', 40, 30.000));
}
}
