How this code executes : 4 ?

Question

public class Program
{
public static void main(String[] args) {
int k=1, sum=0;
while(k!=5){
if((k%2)!=0){
sum+=k;
}
k++;
}
System.out.println(sum);
}
}

Answer 1

iteration 1
k=1
k!=5 is true
(k%2)!=0 is true
sum becomes 1

iteration 2
k=2
k!=5 is true
(k%2)!=0 is false
sum remains 1

iteration 3
k=3
k!=5 is true
(k%2)!=0 is true
sum becomes 1+3=4

iteration 4
k=4
k!=5 is true
(k%2)!=0 is false
sum remains 4

iteration 5
k=5
k!=5 is false
loop breaks
sum remains 4

Answer 2

k=0 (5 loop), k=1 ( 4 loop) ... calculate from 0 to 5, then k=5 loop breake.

Answer 3

ans is 4
