The Get() Method Returns The Element At The Specified Position In This List.

Note that these operations may execute in time proportional to the index value for some implementations (the linkedlist class, for example). The parameter 'index' represents the index of the elements to return. The classes that implement the list interface in java are linkedlist, arraylist, vector, stack, etc.

Thus, Iterating Over The Elements In A List Is Typically Preferable To.

The sublist() method of list interface returns a view of the portion of this list between the inclusive and exclusive parameters. Given a list of integers and we have to access/retrieve element/object from given index from the list in java. Next, the call foreach () method and gets the index value from the int stream.
