Convert binary to decimal Program Plan: Import necessary stream packages into program. Define the class named “Main”. Define main method. Prompt the user for binary number. Initialize the object “obj” for “Scanner” class. Define the variable “binary” and get the value. Call the “toDecimalvalue()” to calculate the decimal number. Calculate the decimal number using “stream” class and print the value on screen. Define the method “toDecimalvalue()” which takes array list as parameter. Declare the character variable “ans” in type of character. Using “for” loop, assign all list values into “ans[]”. Return the value of “ans”.

(Financial: credit card number validation) Credit card numbers follow certain pat- terns. A credit card number must have between 13 and 16 digits. It must start with: 4 for Visa cards 5 for Master cards 37 for American Express cards 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or whether a credit card is scanned correctly by a scanner. Credit card numbers are generated following this validity check, commonly known as the Luhn check or the Mod 10 check, which can be described as follows (for illustra- tion, consider the card number 4388576018402626): 1. Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number. 4388576018402626 → 2 * 2 = 4 → 2 * 2 = 4 → 4 * 2 = 8 → 1 * 2 = 2 6 * 2 = 12 (1+ 2 = 3) → 5 * 2 = 10 (1+ 0 = 1) → 8 * 2 = 16 (1 + 6 = 7) → 4 * 2 = 8
