In this tutorial, we will illustrate how to concatenate multiple collections into one logical collection. We'll be exploring five different approaches - two using Java 8, one using Guava, one using Apache Commons Collections, and one using only the standard Java 7 SDK. In the examples that follow, let's consider the following collections: All you're doing is adding every element inside each value for list, to one ArrayList named combined. Just iterate through all the inner lists of a using foreach loop and addAll to result arraylist. ArrayList merged = new ArrayList (); for (ArrayList list : a) merged.addAll (list);

2. Merging Two ArrayLists excluding Duplicate Elements. To get a merged list minus duplicate elements, we have two approaches: 2.1. Using LinkedHashSet. The Java Sets allow only unique elements. When we push both lists in a Set and the Set will represent a list of all unique elements combined. In our example, we are using LinkedHashSet because it will preserve the element's order as well.
