+import java.util.*; // Importing utility classes for List and Arrays
+import java.util.stream.IntStream; // Importing IntStream for range and mapping
+import java.util.stream.Collectors; // Importing Collectors for collecting stream results
+
+public <A, B> List<List<Object>> zip(List<A> list1, List<B> list2) {
+    // Create pairs by iterating through the indices of both lists
+    return IntStream.range(0, Math.min(list1.size(), list2.size())) // Limit the range to the smaller list
+            .mapToObj(i -> Arrays.asList(list1.get(i), list2.get(i))) // Pair elements from both lists at index i
+            .collect(Collectors.toList()); // Collect the pairs into a List
+}
+
+// Usage:
+List<String> arr1 = Arrays.asList("a", "b", "c");
+List<Integer> arr2 = Arrays.asList(1, 2, 3);
+List<List<Object>> zipped = zip(arr1, arr2);
+
+System.out.println(zipped); // Output: [[a, 1], [b, 2], [c, 3]]
