Question

List all the internal contents of a class in Java.​

Answer 1

Positional access — manipulates elements based on their numerical position in the list. This includes methods such as get, set, add, addAll, and remove.

Search — searches for a specified object in the list and returns its numerical position. Search methods include indexOf and lastIndexOf.

Iteration — extends Iterator semantics to take advantage of the list's sequential nature. The listIterator methods provide this behavior.

Range-view — The sublist method performs arbitrary range operations on the list.

The Java platform contains two general-purpose List implementations. ArrayList, which is usually the better-performing implementation, and LinkedList which offers better performance under certain circumstances.
