Asking for loop code

Question

need to ask why and how?thank you
int j, sum= -44;
for(j=0; <=20; j+=5){
sum+=j+1;
System.out.println(sum);
}
Output is:-43,-32,-26,-10,11

Answer 1

j will be 0,5,10,15,20 & then loop stops
1st cycle) sum = -44+(0+1)=-43
2nd cycle) sum=-43+(5+1)=-37
3rd cycle)sum= -37+(10+1)=-26
4th cycle)sum= -26+(15+1)=-10
5th cycle)sum=-10+(20+1)=11

Answer 2

oh yes it's -37 and j<=20, sorry for my mistakes!! thank u I think I get it now😀

Answer 3

Do you mean the output is:
-43
-37
-26
-10
11

not -32?

And the for loop condition is incomplete, so I'm assuming you meant j<=20, which would make sense then.

j = 0
j+1 = 1
-44 +1 = -43
j+=5 (0+5) j = 5
j+1 = 6
-43 + 6 = -37
j+=5 (5+5) j = 10
j+1 = 11
-37 + 11 = -26
j+=5 (10+5) j = 15
j+1 = 16
-26 + 16 = -10
j+=5 (15+5) j = 20
j+1 = 21
-10 + 21 = 11
j+=5 (20+5) j = 25
j is greater than 20 loop exits
