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 preserve the element’sorder as well. ArrayList<String>listOne=newArrayList<>(Arrays.asList("a","...

We have now seen how to implement three popular sorting methods in Java. Bubble Sort: Simple but not very fast for large arrays. Merge Sort: Efficient and divides the array into smaller parts, sorting them before merging. Quick Sort: Fast on average, using a pivot to divide the array into...
