Loops
The second type of control flow statement is loops. With loops, you can repeat the same logic multiple times. So, if you have a loop from 1 to 10, you always add 1, and you repeat this statement 10 times (it's like counting out loud).
There are three types of loops that you can use in Apex:
- The do...while loops
- The while loops
- The for loops
All these types of loops allow the following statements for loop control structures:
- break: This statement exits the entire loop (for example, if you need to find a specific item in a loop).
- continue: This interrupts the execution of the current code and skips to the next iteration of the loop.
