java - Hashtag Multiple -


i trying find number of unique hashtags in tweet inputted user. example, if inputs "#one #seven #one purple green #red", show 3 unique hashtags "#one, #seven, #red". in code, can 1 tweet, cannot figure out how input multiple tweets , find unique hashtags them. 

package edu.bsu.cs121.jmgibson;  import java.util.arraylist; import java.util.arrays; import java.util.hashset; import java.util.scanner; import java.util.set;  public class tweet {   public static void main(string[] args) {     scanner scanner = new scanner(system.in);     system.out.println("please enter tweet");     string tweet = scanner.nextline();     set<string> hashtags = gethashtags(tweet);           system.out.println(hashtags.tostring()); }  public static set<string> gethashtags(string tweet) {     string[] words = tweet.split(" ");     set<string> hashtags = new hashset<string>();     (string word : words) {         if (word.startswith("#")) {             hashtags.add(word);         }     }     return hashtags; } }

i don't want homework you, i'll offer suggestions:

  1. in main(), you'll need loop asks input , makes calls gethashtags().

  2. instead of creating new hashset inside of gethashtags(), create 1 in main() (outside of loop), , pass in.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
