Find the words start from a special character java

Question

I want to find the words that start with a \"#\" sign in a string in java. There can be spaces between the sign and the word as well.

The string \"hi #how are # yo

Answer 1

Here's a non-regular expression approach...

1. Replace all occurrences of a # followed by a space in your string with a #

   myString.replaceAll("\s#", "#")

2. NOw split the string into tokens using the space as your delimited character

   String[] words = myString.split(" ")

3. Finally iterate over your words and check for the leading character

   word.startsWith("#")
