What actions need to be performed to apply the For Each construct in a loop?

To use the For Each construct in Java, you need:

1. To have a collection or array to iterate over.
2. To use the syntax:

for (Type element : collection) {
    // actions with the element
}

For example:

int[] numbers = {1, 2, 3, 4};
for (int num : numbers) {
    System.out.println(num);
}

This allows you to iterate over all elements of the array without needing to use an index.
