Lesson: 21 | For Loop

Notes

When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop:

Statement 1 is executed (one time) before the execution of the code block.

Statement 2 defines the condition for executing the code block.

Statement 3 is executed (every time) after the code block has been executed.

for (Integer i = 0; i < 5; i++) {
  System.debug(i);
}

Integer i;
for (i = 0; i <= 10; i = i + 2) {
  System.debug(i);
}

Integer i;
for (i = 1; i <= 11; i = i + 2) {
  System.debug(i);
}

for (Integer i = 0; i <= 50; i+=5) {
  System.debug(i);
}
