Question

I want to extract any words immediately after the # character in a String, and store them in a String[] array.

For example, if this is my String…

"Array is the most #important thing in any programming #language"

Then I want to extract the following words into a String[] array…

"important"
"language"

Could someone please offer suggestions for achieving this.

Answer 1

try this –

String str="#important thing in #any programming #7 #& ";
Pattern MY_PATTERN = Pattern.compile("#(\\S+)");
Matcher mat = MY_PATTERN.matcher(str);
List<String> strs=new ArrayList<String>();
while (mat.find()) {
  //System.out.println(mat.group(1));
  strs.add(mat.group(1));
}

out put –

important
any
7
&
