📝 The Problem: Traditional Looping

import java.util.ArrayList;
import java.util.List;

public class NumberProcessor {
    public static List<Integer> doubleNumbers(List<Integer> numbers) {
        List<Integer> result = new ArrayList<>();
        for (Integer number : numbers) {
            result.add(number * 2);
        }
        return result;
    }
}

✅ The Solution: Java Streams

import java.util.List;
import java.util.stream.Collectors;

public class NumberProcessor {
    public static List<Integer> doubleNumbers(List<Integer> numbers) {
        return…
