This is a Java program which asks you to identify whether your birthday appears in five different sets of numbers.
Each set represents some specific range of dates so that every possible day of the month appears in a unique combination of these sets.
Each day of the month can be represented in binary form using 5 bits, which organizes the days in such a way that each day can be identified by checking whether it appears in specific sets.
The program displays each set to the user one by one and reads the user’s response to each set (Yes or No).
Based on the answers, the program adds specific values to a variable day that leverages binary logic and sums up these values to determine the exact day.
The logic behind adding the values 1, 2, 4, 8, and 16 corresponds directly to the binary numbering system, which is the foundation of how computers process and store information.
The method of adding 1, 2, 4, 8, and 16 is tied to the binary system, where each set represents a different bit position in the binary number corresponding to your birthday.
After answering questions for all five sets, the program reveals your birthday, which has been calculated using simple arithmetic.
This is not only a fun way to guess your birthday but also a practical demonstration of how binary logic underpins many applications.
The same logic can be found in real-life applications such as decision trees, binary search algorithms, interactive games, etc.
