{
     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').

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);
        }
    }
}

JavaScript String split() Method, The split() method is used to split a string into an array of substrings, and returns the new array. Tip: If an empty string ("") is used as the separator, the string is  1b) Split a string delimited by characters and return all elements: The return value contains these 9 elements: <><ONE><><TWO><><><THREE><><> 1c) Split a string delimited by characters and return all non-empty elements: The return value contains these 3 elements: <ONE><TWO><THREE> 1d) Split a string delimited by characters and return 2 elements: The return value contains these 2 elements: <><ONE,,TWO,,,THREE,,> 1e) Split a string delimited by characters and return 2 non-empty elements: The

The readLine method already reads line-by-line. There will be no \n characters in this string.

Try this instead:

ArrayList<String> itemList = new ArrayList<String>();
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String str;
while ((str = in.readLine()) != null) {
    itemList.add(str);
}
in.close();

Split() String method in Java with examples, Parameters: regex - a delimiting regular expression Limit - the result threshold Returns: An array of strings computed by splitting the given string.

It is also used to split strings on other specific characters or strings.

this my code and its work for me

private class DownloadWebPageTask extends AsyncTask<String, Void, String> {
    @Override
    protected String doInBackground(String... urls) {
        String response = "";
        for (String url : urls) {
            DefaultHttpClient client = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet(url);
            ArrayList<String> itemList = new ArrayList<String>();
            try {
                HttpResponse execute = client.execute(httpGet);
                InputStream content = execute.getEntity().getContent();

                BufferedReader buffer = new BufferedReader(
                        new InputStreamReader(content, "iso-8859-1"));
                StringBuilder sb = new StringBuilder();

                String s = null;

                while ((s = buffer.readLine()) != null) {

                    itemList.add(s);


                }

                response = itemList.get(0);
                content.close();

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return response;
    }

    @Override
    protected void onPostExecute(String result) {
        textView.setText(Html.fromHtml(result));
    }
}

public void readWebpage(View view) {
    DownloadWebPageTask task = new DownloadWebPageTask();
    task.execute(new String[] { "http://www.yourURL.com" });

}

readWebpage function is onclick function I create in my button xml like this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

<Button android:layout_height="wrap_content" android:layout_width="match_parent" android:id="@+id/readWebpage" android:onClick="readWebpage" android:text="Load Webpage"></Button>
<TextView android:id="@+id/TextView01" android:layout_width="match_parent" android:layout_height="match_parent" android:text="Example Text"></TextView>

in my code I try to get the first line so I use itemList.get(0) if you want to get another line just change the index like itemList.get(1) or itemList.get(n)

Python String, split() method returns a list of strings after breaking the given string by the specified separator. Syntax : str.split(separator, maxsplit).

use Arraylist for this..

ArrayList<String> items= new ArrayList<String>();

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

 for(int i=0;i<items.size;i++)
 {
    System.out.println("item name "+items.get(i));
 }
