7,414 PointsUse of the "for" loop in this video doesn't make sense to me.
Im not sure if its bad explaining or my interpretation of this but could someone explain the for loop in this video as Craig makes around 4:30. I am use to knowing for loops as taking 3 inputs such as:
for (int i = 0; i<10; i++) {
System.out.printf(i);
}

The type of for-loop that Craig is using around 4:30 is called a for-each, or an enhanced for-loop. This type of loop will iterate over each item in an array, rather than using a counter variable like a regular for-loop. The one shown in the video will take mAnswer, split it into individual characters, then go over each letter in it. The char, letter, can then be used inside the loop.
for (char letter: mAnswer.toCharArray()) {
}
