Every collection has its own advantage and disadvantages. Also, each collection has a different usage. Choose according to the data which needs to be stored

Hai As per my knowledge The Java Collections API provides a whole host of data structures, especially since the API was expanded in Java 5 (and again slightly in Java 6) to include concurrent collections. At first, the array of choices can be a little daunting: should I use a HashMap or a LinkedHashMap? When should I use a list or a HashSet? When should I use a TreeMap rather than a HashMap? But with a bit of guidance, the choice needn't be quite so daunting. There are also a few cases where it's difficult to decide because the choice is very arguable. And in other cases, having a clear set of rules of thumb can guide you to an appropriate decision. Thankyou read less
