My first Java program

package ex01;

import java.util.Scanner;

public class Hello {

      

      public static void main (String[] args) {

            Scanner scn  =  new Scanner(System.in);

            System.out.print("Please enter name:");

            String strName = scn.next(); /* declare a string variable named "strName", use scn.next() method to get what string a user entered, then assign to "strName". */

            System.out.println("Hi !" + strName + ",Welcome to Java world!");

            scn.close();

      }

}
