This is a BMI calculator I created using Java with Netbean as platform. Key in the data and it will do the counting for you.

This is a calculator and yes, it does function as a real calculator. My team and I created this Netgear calculator.  It is created with Java and Netbean as the platform. This is the standard version of calculator. 

This is the scientific version of Netgear calculator. It is interchangeable between standard and scientific version.
