Solution: The Scientific Constants Library

Explore how to encapsulate scientific constants in Java classes using public static final fields and create utility methods. Learn to apply static imports to improve code clarity in simulations by combining constants and formulas in a way that mirrors mathematical notation.

We'll cover the following...
// File location: com/space/science/MathConstants.java
package com.space.science;

public class MathConstants {
    public static final double PI = 22.0/7.0;
    public static final double KM_TO_M = 1000.0;

    public static double squareRoot(double val) {
        return Math.sqrt(val);
    }
}
A complete solution of complex calculations simplified with static imports
