Annotations in IntelliJ

I set up Maven and updated the dependencies to add Selenium and TestNG. When I use @Test, I get below errors : 

"Annotations are not allowed here" and "Identifier or type expected " line against @Test

"; expected" and "Expression expected" against line public void login(){

Code : 

package com.qtpselenium.hybrid;

import org.testng.annotations.Test;

public class LoginTest {
    public static void main(String[] args) {
        @Test
         public void login(){
            System.out.printf("Login");
        }
    }
}
