Thread: Isolating a single word from user input...

I need to isolate a word that starts with a hashtag (#) from a string of user input. For example if the user enters "Hi how #are you today" i need the program to print out "#are".

My thought process was to try to isolate the substring from the index of the # to the next space, but I do not know how to get it to recognize the index of the next space instead of just the first space in the string. So my code for this action looks a little like this right now:

tweet = keyboard.nextLine();
int pos = tweet.indexOf("#");
String hashtag = tweet.substring(pos, " ");
System.out.println("Hashtag: " + hashtag);

ANY advice would be helpful. Also I have not learned about loops or arrays yet so if there is anyway to do this without them that would be great!

get it to recognize the index of the next space

Read the API doc for the indexOf() method. It's all there.

THANK YOU GUYS! i hadn't thought of trying it that way! Needless to say, it works now!
