I understand the for loop here; I don't understand how the if else works here....

Question

int result = 0;
for (int i = 0; i < 5; i++) {
if (i == 3) {
result += 10;
}
else {
result += i;
}
}
System.out.println (result);

/* The for loop gives 0 1 2 3 4 values; so which do we take*/

Answer 1

inside "{ }" of "if" only run when condition inside "( )" meets. otherwise it will run "else".

more explanation:
the loop will be 5 times, and "i" will be 0 - 1 - 2 - 3 - 4.

this will run 5 times and "i" value base on that increment.
if (i == 3) {
result += 10;
}
else {
result += i;
}

there is condition "i == 3", so when "i" is 3, "result += 10;" will run, anything else "result += i;"
