What are the differences between a foreach loop and a for loop in Java?

In Java, a foreach loop is used to iterate over elements in a collection or array, while a for loop gives you more control over the iteration process, allowing you to specify the index.

Can you give me an example of both loops?

Sure! For a for loop:

for(int i = 0; i < array.length; i++) {
    System.out.println(array[i]);
}

And for a foreach loop:

for(String item : list) {
    System.out.println(item);
}

When should I use one over the other?

Use a foreach loop when you need to iterate through all elements without modifying the collection. Use a for loop when you need to control the index or modify the collection during iteration.

Are there any performance differences?

Generally, the performance difference is negligible for most use cases. However, a for loop can be slightly faster in scenarios where you need to access elements by index.
