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.

System.out.println("Second is grater");

/*
To compare a Double object with another Double object use
int compareTo(Double d) method.
It returns 0 if both the values are equal, returns value less than 0 if
this Double object is less than the argument, and returns value grater
than 0 if this Double object is grater than the argument.

Output would be
First is grater
First is grater
