Question

i have this. public Book[] bookCollection = new Book[20];
public void addBook(String title){

}

how do i add an item to the array in Java?

Answer 1

bookCollection[ x ] = new Book( title );

Where x is an integer between 0 and 19 in this case.

Answer 2

its seems to be something incomplete u havent shown as what item book contains you want to add u just shown an object if its string array then u have to use loop with limit to 20 items and then add to array and there are several methods but i suggest instead of string array u should use linked list its easy to add remove items

Answer 3

sorry instead of you i typed u its Facebook effect ;)
