Convert the following do-while loop into a for loop: int i = 1; int d = 5; do { d = d * 2; System.out.println(d); i++; } while(i <= 5);

int d = 5; int i; for(i = 1; i <= 5; i++) { d = d * 2; System.out.println(d); }

Map the three parts of the loop into the for header: initialisation - i = 1, taken from the declaration condition - i <= 5, copied unchanged update - i++, moved from the body into the header The variable d is not part of the loop control, so it stays declared above the loop. One caution worth stating: a do-while always runs at least once, while a for tests first. Here i starts at 1 and the condition is true immediately, so the two forms behave identically — the output is 10, 20, 40, 80, 160 either way.
