Sum of Number from 1 to N
☕ Java Series – Day 21 | Sum of Numbers Using for Loop
Welcome to Day 21 of the Java Series by LogicLoops26! 🚀
In today's video, we learned how to find the sum of numbers from 1 to N using a for loop in Java.
📚 Topics Covered:
✅ Taking user input using Scanner
✅ Using a for loop
✅ Understanding initialization, condition, and increment
✅ Using an accumulator variable sum
✅ Adding numbers from 1 to N
✅ Step-by-step program explanation
💻 Example:
If the user enters 5:
1 + 2 + 3 + 4 + 5 = 15
Output:
Sum = 15
💡 Key Concept:
The sum variable stores the total value, and during each iteration, the current value of i is added to sum.
🎯 Practice Challenge:
Try writing a Java program to find the sum of all even numbers from 1 to N using a for loop.
