Learn tocompare two ArrayListin Java to find if they contain equal elements. If both lists are unequal, we will find thedifference between the lists. We will also learn to find common as well as different items in each list. Note that the difference between two lists is equal to a third...

To get a merged list minus duplicate elements, we have two approaches: 2.1. UsingLinkedHashSet The JavaSetsallow only unique elements. When we push both lists in aSetand theSetwill represent a list of all unique elements combined. In our example, we are usingLinkedHashSetbecause it will pr...
