JAVA LANGUAGE

How can I create a method with this given pseudocude (Meant to be an array of strings):

public void set(int index, String value) {

// Code to set an element of your string list at specified index

// to the provided value. You cannot set an item beyond that last

// item in the list. Set will only work on elements greater than

// or equal to zero and less than size. Do not add elements to the

// list with set. Display an error if an index is out of bounds. }
