I’m trying to extract the words form a paragraph/string. I searched it out many where but didn’t find relative material. I want to extract words of length 4 from
“I want to have alot of moneys when I am older probably e1X2”
I’m trying to extract using
List<String> words = new ArrayList<String>(); String s = "I want to have alot of moneys when I am older probably."; Pattern p = Pattern.compile("[a-zA-Z']{4,}"); Matcher m = p.matcher(s); while (m.find()) { words.add(m.group()); } System.out.println(words);
The output which am I getting right now
[want, have, alot, moneys, when, older, probably]
but the output must be
[want, have, alot, when]

The simpler way to get the result :
List<String> words=new ArrayList<String>(); String s="I want to have alot of of moneys when I am older probably"; String str[]=s.split(" "); for(int i=0;i<str.length;i++) { if(str[i].length()==4) words.add(str[i]); } System.out.print(words);
