Java Double compare example
This example shows how to compare a Double object with other Double object, Double
with an Object, or two double primitive values using methods provided by
java.lang.Double class.

To compare two double primitive values use
compare(double d1, double d2) method of Double class. This is a static method.
It returns 0 if both the values are equal, returns value less than 0 if
d1 is less than d2, and returns value grater than 0 if d1 is grater than d2.

To compare a Double object with another Double object use
