Question

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String str
while ((str =in.readLine()) != null)
{
     items = str.split("\n");
}
in.close();

String (str) contains data from a text file like:

January

February

March

etc.

Each word is on ag new line.
I want to read the string and separate each word on a new line and store into an array of String objects (this would be the variable named ‘items’).

Answer 1

Actually, BufferedReader.readLine already splits the input based on newlines.

So, where you currently have:

items=str.split("\n");

you only need to append str to your array.

For example, with the infile file holding:

January
February
March
April
May
June

the following program outputs 6 (the size of the array list created):

import java.io.BufferedReader;
import java.io.FileReader;
import java.util.ArrayList;
class Test {
    public static void main (String[] args) {
        try {
            ArrayList<String> itms = new ArrayList<String> ();
            BufferedReader br = new BufferedReader (new FileReader ("infile"));
            String str;
            while ((str = br.readLine()) != null)
                itms.add(str);
            br.close();
            System.out.println (itms.size());
        } catch (Exception e) {
            System.out.println ("Exception: " + e);
        }
    }
}
