java - reading text file against specific words -

i creating tool in java eclipse distinguish whether sentence contains particular word or not.

i using twitter4j tool able search tweets in twitter.

i have used stanford nlp tagger able tag tweets twitter. stored in text file.

here code

public class texttag {   public static void main(string[] args) throws ioexception,  classnotfoundexception {   string tagged;   // initialize tagger  maxenttagger tagger = new maxenttagger("taggers/english-left3words-distsim.tagger");   // sample string  string sample = "output tagged";   //the tagged string  tagged = tagger.tagstring(sample);   //output tagged sample string onto console  //system.out.println(tagged);   /*pick sentences file ouput.txt , store output of  tagged sentences in file entitytagged.txt. */   fileinputstream fstream = new fileinputstream("output.txt");  datainputstream in = new datainputstream(fstream);  bufferedreader br = new bufferedreader(new inputstreamreader(in));   //we pick sentences line line file ouput.txt , store in string sample  while((sample = br.readline())!=null)  {  //tag string  tagged = tagger.tagstring(sample);  filewriter q = new filewriter("entitytagged.txt",true);  bufferedwriter out =new bufferedwriter(q);  //write file entitytagged.txt  out.write(tagged);  out.newline();  out.close();   } 

my next step use tagged tweets entitytagged.txt , compare these string of positive words , negative words.

i have created 2 text files, list of positive words , list of negative words, , goal loop through 10 different tagged tweets in 'entitytagged.txt" file against positive.txt , negative.txt files find out if word comes can distinguish if tweets positive or negative

my end result should have

tweet 1: positive tweet 2: negative tweet 3: negative

etc

at moment, struggling create algorithm can implement this

any appreciated

thank you

here's five-minute algorithm. store positive , negative words delimited strings. loop through words in tweet see if exist in delimited strings. you'll have expand split regex include special characters:

string positivewords = "|nice|happy|great|"; positivewords = positivewords.tolowercase();  string negativewords = "|bad|awful|mean|yuck|sad|"; negativewords = negativewords.tolowercase();  string tweetone = "nice day happy not sad @ all"; tweetone = tweetone.tolowercase();  string[] arrwords = tweetone.split("\\s"); int value = 0; (int i=0; < arrwords.length; i++) {      if (positivewords.indexof("|"+arrwords[i]+"|") != -1) {         system.out.println("pos word(+1): " + arrwords[i]);         value++;     }     if (negativewords.indexof("|"+arrwords[i]+"|") != -1) {         system.out.println("neg word(-1): " + arrwords[i]);         value--;     }             }  system.out.println("positive/negative value: " + value);
