🔥 90 DAYS OF JAVA CHALLENGE
📅 DAY 02/90: Java Operators & Calculations
Welcome to Day 2, developers! 💻🚀
Yesterday, we learned how to store and display information using Java variables. Today, we're going to make our programs perform calculations!
🎯 TODAY'S CHALLENGE: Smart Calculator
Build a Java program that accepts two numbers from the user and performs the following operations:
Addition (+)
Subtraction (-)
Multiplication (*)
Division (/)
Remainder (%)
📌 Requirements:
Use Scanner to accept user input.
Store the numbers in appropriate variables.
Use arithmetic operators to perform the calculations.
Display all five results clearly.
Handle division by zero appropriately.
⭐️ BONUS CHALLENGE
Calculate the average of the two numbers and display the result.
🧪 Example Output

===== SMART CALCULATOR =====
Enter first number: 20
Enter second number: 6

Addition: 26
Subtraction: 14
Multiplication: 120
Division: 3.3333...
Remainder: 2
Average: 13.0
============================

⏳ Time limit: 30–45 minutes
📤 SUBMISSION RULES

🔥 JAVA90 CHALLENGE | DAY 03 ☕️💻
📅 Topic: Conditional Statements in Java
Welcome to Day 3 of our 90 Days of Code Challenge!
Today, we are learning how to make programs think and make decisions using if, else if, else, and switch.
🎯 Today's Challenge: Student Grade Calculator
Write a Java program that:
Accepts a student's score from 0 to 100.
Displays the corresponding grade using these rules:
90–100 → Grade A
80–89 → Grade B
70–79 → Grade C
60–69 → Grade D
Below 60 → Grade F
If the score is below 0 or above 100, display Invalid score!.
💡 Requirements:
Use Scanner to receive input.
Use if-else if-else statements.
Handle invalid scores correctly.
Test your program with different scores.
⏳ Time limit: 30 minutes
📤 Submission: Share your Java source code and a screenshot of your program's output in the group.
🏆 Bonus challenge: Add a message:
Grade A: Excellent!
Grade B: Very Good!
Grade C: Good!
Grade D: Passed!
Grade F: Keep Practicing!
🔥 Remember: Don't just copy code. Understand it, write it, and test it yourself.
