How to find a specific word in sentence in each line?

Question

How to find a specific word in sentence in each line and output will show start from the beginning from specific word plus with small description from each sentence?
For example: I need to find a "+Wednesday+" and "+Thursday+" word in each sentence by line by line from "myfile.txt".
Go ballet class next Wednesday.
On the Wednesday is going to swim class.
We have a meeting on Thursday at Panda's.
Then it will show the output:
Wednesday : ballet class
Wednesday : swim class
Thursday: meeting at Panda's
I am going to figure out in Java console to read from a file for specific word from each line and how to make it output in correct way. I know already to make input/file codes.

Answer 1

I got it and understand much better. Thank you very much. There is a problem with it because I knew how to make
a specific word in sentence but how I should make Output for specific word and some words from sentence.
For example:
Input:
+"On Thursday go to ballet class"+
+"Swim class on Friday one time a month at 2 p.m."+
I used the codes for that:
class FindSchedule{
     String firstline = "On Thursday go to ballet class ";
     String secondline = "Swim class on Friday one time a month ";
     FindSchedule(){
          System.out.println(firstline + findTheIndex("Thursday", firstline));
          System.out.println(secondline + findTheIndex("Friday", secondline));
     public int findTheIndex(String word, String sentence){
          int index;
          index = sentence.indexOf(word);
          return index;
     public static void main (String[] args){
          new FindSchedule();
}The output will be:
Thursday: ballet class
Friday: 14:00 swim class one time a week
Notice that time is changing in output complete different from input.
I need to find out how to extract some words from each sentence for output. Do you know how to do it?
