Join Peggy Fisher for an in-depth discussion in this video Enhanced for Loop, part of Java Essential Training for Students.
- The last topic in this section…is called the Enhanced for Loop.…The Enhanced for Loop works really well…with both arrays and ArrayLists.…After creating an array, you can easily…traverse the array using the Enhanced for Loop.…The syntax is a little strange at first,…but it reduces the coding needed…to go through the entire array.…Some quick notes about the Enhanced for Loop,…it can only be used when you wanna…start at the first element of the array,…and go through all the way to the end.…And another note is that you cannot…have any code in the loop that alters…the contents of the array.…
You can kind of think of it as…a loop that will allow you to read…the elements in an array,…or an array list.…I wanna show you how to use the Enhanced for Loop…with both a regular array, and an ArrayList.…I'm gonna go back to my ArrayExamples,…and I'm gonna show you how we can…use an Enhanced for Loop for a couple of these arrays.…I'll put this at the bottom.…So an Enhanced for Loop looks like this.…It has the word for,…and then you declare the type of objects…
