Why This Java Code Causes an Infinite Loop | Debugging Explained

📢 Description:
Let’s break down this code and understand why it leads to an infinite loop!

Problem:
What is the output of the following code?

Java
Copy
int sum = 0;
int k = 1;
while (sum - 12 || k - 4)
sum += k;
Options:
A) 6
B) 10
C) 12
D) Infinite loop

Quick Breakdown:
1️⃣ Analyzing the Condition:
The while loop runs as long as sum - 12 OR k - 4.

sum starts at 0 and k starts at 1.
2️⃣ What Happens Inside the Loop?

Inside the loop, sum += k keeps adding k to sum, but k never changes, so sum keeps increasing by 1.
3️⃣ Infinite Loop Condition:

The condition sum - 12 will always be true since sum keeps increasing by 1, and k - 4 is also true because k is always 1.
This means the loop never stops.
4️⃣ Answer:
The correct answer is Option D: Infinite loop. The loop keeps running forever because there's no update to k, and the condition never becomes false.

🚀 Key Takeaways:

Without updating k, the loop becomes an infinite loop.
Always ensure that the loop’s conditions will eventually be satisfied to prevent infinite loops.
