Can anyone explain to me. What is happening in this code?

public class Program { public static void main(String[] args) { boolean b=true; for(int i=0;i<10;i++){ if(b=!b){ System.out.print(i); } } } }

Sorry Atul I think so I provided you the reverse one 0=false and 1=true. Sorry everyone for it. I was utterly confused

why 3? where did you see this in the program? have you checked the launch? the program outputs all odd numbers.

for(variable; condition; addition) <-- for starts a loop it checks if the variable(i) is <= 3 (i (<) less than or (=) equal to 3) while the variable(i) is less than 3 it adds +1 to the variable i (i++) i dont know if this is the answer you wanted but i'm not good at explaining

🤭 It looks like you need to come up with another explanation

I understand the logic as follows: since the if expression is executed only when the condition is true, and the string b =!b at each iteration of the loop changes the truth to untruth and vice versa, then in the end it turns out that i is printed every other time. brilliant!

Yes Ярослав Вернигора(Yaroslav Vernigora) inshort it skips one iteration, which looks like odd. I get to know about this =! After looking this code 😅

Ah! Error... use relational operator... instead of assignment in if statement
