Day 2: Leap Years

---

Exercise

Write a Java program to determine if a given year is a leap year.

Introduction

A year is a leap year if it conforms to either of the following conditions:

• It is divisible by 400
• It is divisible by 4 but not divisible by 100

Algorithm

1. Implement the core functionality using a text-based interface for I/O.
2. Build a GUI to wrap your implementation.

Resources

• Main.java (text-based interface)
• Leap year (Wikipedia)

Hints

Use the modulo (%) operator to determine if a number is evenly divisible by another value. For example:

The first line is equal to 0 since 12 is evenly divisible by 3. The second line is equal to 2 because the remainder of 42 / 10 is 2.
