Splitting a long sentence to a short one when a certain word is found in Java

Greetings All;

I have a LinkedList of type String which contain some words like [from, to, in, then, however] and I have a text file which contain long sentences. what i want to do is to split those sentences in shorter sentences when one of the above words is found.

what I have did so far that I made a linked list that contains the words, and another linked list that contain the long sentences in the file. I don't know how to split the long sentence?

I have tried this:

int indexofsw = 0;
       for (int k = 0; k < LongSentence.size(); k++) {
                for (int j = 0; j < SWords.size(); j++) {
                    if (LongSentence.get(k).contains(SWords.get(j))== true) {
                        indexofsw = LongSentence.get(k).indexOf(SWords.get(j));
                        System.out.println(LongSentence.get(k).substring(k,indexofsw));
                        break;

                    }
                }
            }

but it doesn't returns a shorter sentence.

Any Ideas please?

Try using replace:

public class test {
  public static void main(String[] args){
    String[] splitWords = {"to", "in", "from", "then"};
    String string = "this from that";
    for (String splitWord : splitWords) {
      string = string.replace(" " + splitWord + " ", System.getProperty("line.separator"));
    }
    System.out.println(string);
  }
}

output:

this
that

test.java, to get you started:

public class test{
  public static void main(String[] args){
    String[] splitWords = {"to", "in", "from", "then"};
    String str = "this from that";
    String[] tmp;
    for (String splitTkn : splitWords){
      tmp = str.split(splitTkn);
      if (tmp.length > 1){
        System.out.println(tmp[0].trim());
        System.out.println(tmp[1].trim());
      }
    }
  }
}

output: 

this
that

Do you mean like?

Set<String> wordsToRemove =
String sentence =
List<String> words = Arrays.asList(sentence.split(" "));
words.removeAll(wordsToRemove);
