For Each vs For Loop: What's the Difference?

Can you explain the difference between a for-each loop and a for loop?

Sure! A for loop iterates over a range of numbers or indices, while a for-each loop iterates directly over elements in a collection.

When should I use a for-each loop instead of a for loop?

Use a for-each loop when you want to simplify your code and avoid dealing with indices, especially when you don't need to modify the collection.

Are there any performance differences between the two?

Yes, for-each loops can be less efficient in some cases, especially with large collections, as they may involve additional overhead.

Can you give me an example of both in Java?

Certainly! For a for loop: for(int i = 0; i < array.length; i++) { System.out.println(array[i]); }. For a for-each loop: `for(String item : array) { System.out.println(item); }.
