Question

How can i add new string into an array of strings like if i have a library class and i create an array of books and i want to add new book object into this array ( the max size is 50)

Answer 1

It sounds like you might be looking for something more like an ArrayList.

Import it from the until package:
import java.util.ArrayList;

You can declare an ArrayList of Strings like this:
ArrayList<String> myList = new ArrayList<String>();

From there, you can add and remove objects as you need. Using the respective ArrayList#add(E e) and ArrayList#remove(int index) methods.

Also, I wrote an implementation of it if you would like to see how it works behind the scenes.
