Your code work fine. I just add little modification:
package practise;
import java.util.Scanner;
public class scanccls {
public static void main(String[] args) {
System.out.println("Enter your name:");
Scanner scan = new Scanner(System.in);
String name="";
name+=scan.nextLine();
scan.close();
System.out.println("Your name is :"+name);
}
}
