Course: AP® Computer Science A Shows up in: Unit 2: Selection and Iteration
An iterative statement whose header has three parts: the initialization (runs once), the Boolean expression (checked before each iteration) and the update (after each iteration).
Appears in the course and exam description (CED): 2.8.A.12.8.A.22.8.A.3
for (int i = a; i < b; i++) runs b - a times. Any for loop can be rewritten as an equivalent while loop, and the reverse.
int sum = 0;
for (int n = 2; n <= 10; n += 2) {
sum += n;
}
System.out.println(sum);
