## Comparable Interface

Objects that have an ordering are compared using the compareTo() method.

### 5. Natural Order

Answer:five.compareTo( ten ) is negative.The declaration of the two Integer variables looks wrong, but they are actually correct. Autoboxing automatically constructs Integer objects for the two primitive integers.

# Natural Order

Objects that implement compareTo() can be arranged into a natural order. This order can be visualized as an arrangement of objects from left to right as on a number line.

The strings in the picture are arranged left to right in dictionary order.

If an object A is left of another object B, then

objectA.compareTo(objectB)

is negative. For example, X.compareTo("orange") is negative for all the fruit X left of "orange".

Question 5:What is "grape".compareTo( "banana" );
