Objective:

Write a program that accepts two four-digit binary numbers, converts them to decimal values, adds them together, and prints both the decimal values and the result of the addition.

Requirements:

• Functionality. (80pts)
• No Syntax, Major Run-Time, or Major Logic Errors. (80pts*)
• *Code that cannot be compiled due to syntax errors is nonfunctional code and will receive no points for this entire section.
• *Code that cannot be executed or tested due to major run-time or logic errors is nonfunctional code and will receive no points for this entire section.
• Clear and Easy-To-Use Interface. (10pts)
• Users should easily understand what the program does and how to use it.
• Users should be prompted for input and should be able to enter data easily.
• Users should be presented with output after major functions, operations, or calculations.
• All the above must apply for full credit.
• Users must be able to enter a 4-bit binary number in some way. (10pts)
• No error checking is needed here and you may assume that users will only enter 0’s and 1’s, and they will only enter 4 bits.
• Binary to Decimal Conversion (50pts)
• You may assume that users will only give numbers that add up to 15.
• See the section Hint for more details.
• Adding Values (10pts)
• Both decimal values must be added together and printed out.
• You may NOT use Integer.parseInt(<<STRING>>, 2) or any automatic converter (80pts*).
• *The use of specifically Integer.parseInt(<<STRING>>,2) will result in a 0 for this entire section.
• You may use Integer.parseInt(<<STRING>>).
• Coding Style. (10pts)
• Readable Code
• Meaningful identifiers for data and methods.
• Proper indentation that clearly identifies statements within the body of a class, a method, a branching statement, a loop statement, etc.
• All the above must apply for full credit.
• Comments. (10pts)
• Your name in the file. (5pts)
• At least 5 meaningful comments in addition to your name. These must describe the function of the code it is near. (5pts)

Hint:

A simple way to convert a binary value to a decimal value.

1. Multiply each binary digit by its corresponding base 2 placement value.

Binary Digit	b0	b1	b2	b3
Base 2 Value	2^3	2^2	2^1	2^0
Result	b0 x 2^3	b1 x 2^2	b2 x 2^1	b3 x 2^0

Example:

Binary Digit	0	1	1	1
Base 2 Value	2^3	2^2	2^1	2^0
Result	0	4	2	1

2. Add the values together to get the decimal value.

Binary Value = b₀ x 2³ + b₁ x 2² + b₂ x 2¹ + b₃ x 2⁰

Example:

Binary Value = 0 + 4 + 2 + 1 = 7
