Fundamental difference between List and Set in Java is allowing duplicate elements. List in Java allows duplicates while Set does not allow any duplicate.
2) List allows duplicates while Set doesn’t allow duplicate elements. All the elements of a Set should be unique if you try to insert the duplicate element in Set it would replace the existing value. 3) List implementations:ArrayList,LinkedListetc. Set implementations:HashSet,LinkedHashSet,Tree...
In this guide, you will learndifference between ArrayList and LinkedList in Java.ArrayListandLinkedListboth implements List interface and their methods and results are almost identical. However there are few differences between them which make one better over another on case to case basis. ArrayList V...
Based upon our understanding of the difference between Set, List and Map we can now decide when to use List, Set or Map in Java. 1. If you need to access elements frequently by using the index than List is a way to go. Its implementation e.g. ArrayList provides faster access if you...
