What are the differences between for-each and for loops in Java?

In Java, a for-each loop is used to iterate over elements in a collection or array, while a traditional for loop gives you more control over the iteration process.

Can you give me an example of both?

Sure! For-each loop: for (String item : list) { System.out.println(item); } and for loop: for (int i = 0; i < list.size(); i++) { System.out.println(list.get(i)); }.

When should I use one over the other?

Use for-each when you need to iterate through all elements without modifying the collection. Use for loop when you need index access or to modify the collection.

Are there any performance differences?

Generally, for-each loops are more readable and can be optimized by the compiler, but for loops may be slightly faster in some cases due to less overhead.
