Java Pre/Post Increment Trap That Fools EVERYONE! #coding #javadeveloper #shorts
4Think you understand Java operators? π€ This tricky question has stumped thousands of developers!
We have: int i = 5;
Then: ++i + i++ + ++i
What does this print? And what's the final value of i? π§
This demonstrates Java's pre-increment (++i) vs post-increment (i++) behavior that confuses even experienced programmers!
β‘ Pre-increment: Increments FIRST, then returns value
β‘ Post-increment: Returns value FIRST, then increments
Drop your guess in the comments before watching the full explanation! π
The answer will absolutely blow your mind! π€―

BREAKDOWN:
++i + i++ + ++i with i = 5
Step 1: ++i (pre-increment)
i becomes 6, returns 6
Step 2: i++ (post-increment)
Returns current value 6, then i becomes 7
Step 3: ++i (pre-increment)
i becomes 8, returns 8
Result: 6 + 6 + 8 = 20
Final i value: 8
