* Einstein’s famous formula E = MC2 gives the amount of energy released by the complete conversion of matter of mass M into energy E. If M represents the mass in kilograms and C represents the speed of light in meters per second (3.0 * 108 m/s), then the result is in the energy unit Joules. It takes 36000 Joules to light a 100 watt light bulb for an hour. Write a Java program that calculates the energy and the number of light bulbs that could be powered by a given mass of matter. Input a double value from the keyboard, and use scientific notation (E notation) and printf statements. Output should look similar to below.

Sample Run:
Enter the mass in kg: 0.01
This mass could provide 9E+14 Joules of energy.
It could power 2.5E+09 100 watt light bulbs for an hour.

* Angles are often measured in degrees (°), minutes ('), and seconds ("). There are 360 degrees in a circle, 60 minutes in one degree, and 60 seconds in one minute. Write a Java program that reads two angular measurements given in degrees, minutes, and seconds, and then calculates and displays their sum. Format the output with appropriate symbols (°,',").

Output should look similar to below.
Note: Use Unicode values for the symbols.

* Have you heard of the Fizz Buzz problem? Some businesses claim they interview Computer Science graduates they can't solve the Fizz Buzz problem. Write a Java program that prints asks the user to enter a positive value (1 less than or equal to 200) and print each number up to that line, 1 per line with the following changes (SNAP CRACKLE POP).
• If a number is divisible by 2 (but not 3 or 5) print out SNAP instead of the integer.
• If a number is divisible by 3 (but not 2 or 5) print out CRACKLE instead of the integer.
• If a number is divisible by 5 (but not 2 or 3) print out POP instead of the integer.
• If a number is divisible by 2 and 3 (but not 5) print out SNAPCRACKLE instead of the integer.
• If a number is divisible by 2 and 5 (but not 3) print out SNAPPOP instead of the integer.
• If a number is divisible by 3 and 5 (but not 2) print out CRACKLEPOP instead of the integer.
• If a number is divisible by 2, 3, and 5 print out SNAPCRACKLEPOP instead of the integer.

Error check inputs. Output should look similar to below.
