regex count for matching in java
import java.util.regex.*;
class Test {
public static void main(String[] args) {
String hello = "HelloxxxHelloxxxHello";
Pattern pattern = Pattern.compile("Hello");
Matcher matcher = pattern.matcher(hello);
int count = 0;
while (matcher.find())
count++;
System.out.println(count); // prints 3
}
}count matches with regex
use regex::Regex;
fn main() {
// count matches with regex
let re = Regex::new(r"(?i)th").unwrap();
let result = re.find_iter("The three truths.").count();
println!("result = {}", result); // 3
