    Smile Display every second world from file.

    I have a file which contains a sentence "Alina ma pingwina a w basenie delfina". So my program should show Alina/pingwina/w/delfina.
    My code looks like this:
    import java.io.BufferedReader;
    import java.io.FileReader;
    import java.io.IOException;
    import java.util.ArrayList;
    import java.util.List;
    public class zad679 {
        public static void main(String[] args) {
            try {
                FileReader fileReader = new FileReader("src/zad679/test.txt");
                BufferedReader bufferedReader = new BufferedReader(fileReader);
                String content;
     
                List<String> l = new ArrayList<String>();
                while ((content = bufferedReader.readLine()) != null) {
                    l.add(content);
                    for (int i =0; i < l.size(); i += 2) {
                        System.out.println(l.get(i) + "/");
                    }
                }
                fileReader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
     
        }
    }
    And the result is:
    Alina ma pingwina a w basenie delfina/

    So the sentence is just like in file, program doesn't display every second world from file like it should. What am I missing, how to fix it? Thank you for your help in advance

    Default Re: Display every second world from file.

    like it should.
    Where does the program split the line that is read into the separate words you want to see?

    The Scanner class has methods to read the input one word/token at a time.
    The String class has the split method that can be used to separate the words/tokens on each line.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
