public class FindingWordsSpecific {
     static String[] days = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "every Tuesday"};
  public static void main( String args[] ) throws IOException {
           // the file must be called 'myfile.txt'
           String s = "myfile.txt";
           File f = new File(s);
           if (!f.exists())
                System.out.println("\'" + s + "\' does not exit. Bye!");
                return;
           BufferedReader inputFile = new BufferedReader(new FileReader(s));
           String line;
           int nLines = 0;
           while ((line = inputFile.readLine()) != null)
                nLines++;
               System.out.println(findTheIndex(line));     
           inputFile.close();
       public static String findTheIndex(String sentence){
            String result = "";
            String[] s = sentence.split("\\s");
          for (String s1: s){
               for (String s2: days){
                    if (s1.equalsIgnoreCase(s2)) {
                         if(s2.matches("every Tuesday")){
                                         }else if (s2.matches("every Wednesday")){
                                          }What is wrong with it because I tried to find "every Tuesday" in
myfile.txt: "Go fishing every Tuesday and every Wednesday"
There is big problem with split statement because it takes each word not more than a word.
I need to have "every Tuesday" not "Tuesday". How to make it correct codes?

Answer 1

I am going to give you a picture of how the output will look.
Here are two sentences from myfile.txt:
Go fishing every Tuesday and every Wednesday
Meet with research students on Thursday
I need to read from myfile.txt and to find specific words in each sentences like this output:
Every Tuesday : Go fishing
Every Wednesday : Go fishing
Thursday : Meet with research students
Ok. make sense? Now I am trying to figure out how to find specific words in each sentence from myfile.txt.
That is why I have difficult with the splits statement and loops. Like this:
       public static String findTheIndex(String sentence){
            String result = "";
            String[] s = sentence.split("\\s");
          for (String s1: s){
               for (String s2: days){
                    if (s1.equalsIgnoreCase(s2)) {
                         if(s2.matches("every Tuesday")){
                         }else if(s2.matches("every Wednesday")){
                         }else if(s2.matches("Thursday")){
                         }else{
                              System.out.println("That sentence is not working");
            return result;
  }So look at the "Thursday" it is working the output because I have split statement to give me only one word not more than
a word in sentence. So there is big problem with more than a word in sentence like this "every Tuesday" and it won't work at all because of split. Could you please help me how to do that? I appreciated for that help. Thanks.
