here is what i have written so far for your clarification that it not an assignment. Its only a problem in a java ebook.

So, what's your question. Just posting a load of code isn't very helpful.

So, what's your question. Just posting a load of code isn't very helpful.

i want to write a java program that will receive the first name ,last name,age,complexion (fair/dark),weight (kg)and height (m2) of 5 individuals; calculate their body mass index(BMI) and display each name and their respective information (including the BMI) accordingly. (BMl)=height/weight . So am having problems with the divsion syntax on how to place it on the calculateGPA.class apect. I will be very grateful if you could help me.

You assign 0 to both height and weight, then you divide height by weight. That's not going to work, is it? And if you want a double result you can't divide an int by an int (even if they were non-zero). Read up on Java's numeric data types, particularly how you convert one to another: http/www.i-programmer.info/ebooks/modern-java/5423-java-data-types-numeric-data.html

thanks you alot for everything

but sir if i try running the program, it tells me that height and weigth is already defined in main(String[]) and i don't if a functions (including main( )) can be used to execute the program and pls can u just correct the lines for me?

Reproduce the exact error message that you get.

If you are learning Java from an eBook then surely you want to understand what you are doing rather than just being given some working code. I'm afraid it does begin to sound as if this is a class assignment. If not, study the basics again before attempting this excercise.

am using a book title "java-how to program(2009)" and what they did was that the only talked about arraylist without how to add the division, addition or multiplication syntax in an array. So i decided to learn it on my own by the help of search engine and other forum which the have not be able to really explain it for me in details and that is why am desperately in need of help to be able to achieve that which i have spend time and resources looking for to understand it.
