This function does not support "break;" nor "continue;". Use "return true;" instead of continue; and "return false;" for "break;". Also, you always need to put "return true;" at the end.

	@FunctionalInterface
    public interface IndexedConsumer<T> {
        // Return true to continue, false to break
        boolean accept(int index, T item);
    }

    public static <T> void forEachIndexed(List<T> list, IndexedConsumer<T> action) {
        for (int i = 0; i < list.size(); i++) {
            if (!action.accept(i, list.get(i))) {
                break;
            }
        }
    }

// USAGE EXAMPLE:
List myList = Arrays.asList("Apple", "Banana", "Strawberry");

forEachIndexed(myList, (index, value) -> {
	System.out.println("Index: " + index + ", Value: " + value);
	return true;
});
