Answer:

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, like on a number line.

If an object A is left of another object B in this ordering, then

objectA.compareTo(objectB)

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

What is "grape".compareTo( "banana" );
