Notes

In Apex, which is a programming language used by Salesforce for building custom applications, a "for" loop is used to iterate over a collection of items, such as a list or a set. Apex supports three types of "for" loops: the traditional "for" loop, the "for-each" loop, and the "for" loop with a list or set.

for (initialization; condition; increment/decrement) {
    // Code to be executed in each iteration
}

Here are some examples:

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

Output:

Iteration 0

Iteration 1

Iteration 2

Iteration 3

Iteration 4
