Program 2 State Electricity Board calculates the electricity bill depending on the previous month and
current month meter reading. The amount generated depends on the following criteria.

Units(present-previous) Per unit rate
--------------------------------------- -------------------
100 units or below ` 2.25 / Unit
Next 250 units ` 3.50 / Unit
Next 250 units ` 4.75 / Unit
More than 600 units ` 6 / Unit
Write a Java program to generate the bill after taking Month name, Name of the consumer,
Previous and Current meter reading from the user. The bill should be generated in the
following format.
