Resource leak: 'scn' is never closed

#1

public static void main(String[] args) {

	Scanner scn = new Scanner (System.in);
	

	int n = scn.nextInt();

	if (n % 2 == 0) {

		System.out.println("even");

	} else {

		System.out.println("odd");

	}

}

This programmer is not sunning and there is a yellow headline below of scn
So please check

#2

And when I press ctrl+f11 it’s showing running but didn’t show console

#3

add these 2

import java.util.*;
public class Main{

also you can add scn.close() at the end of program to remove the warning
