how to extract the previous or next string of matched with regex in java?

Question

final String str = "I want to get previous or next string";
final Matcher matcher = Pattern.compile("or").matcher(str);
if(matcher.find()){
System.out.println(str.substring(matcher.end()).trim());
}

I want to get:"previous" or "next" strings

output: next string

Why not use a positive look behind for "or" and capture `"next String"? — TheLostMind, Mar 08 '18 at 08:48
