“Possible loss of precision” in my Java program

Question

I\'m new to Java. I wrote the following code:

import java.io.*;
import java.lang.*;

public class distravel
{
    public static void main(String args[])
             


        

Answer 1

Don't use floats in your floating point math calculations unless you have a specific reason for doing so (you don't). The overhead for the preferred type, double, is not much higher and the benefit in accuracy is great.
