How to get StringBuilder From user

How to get StringBuilder From user

how can i get StringBuilder from users through Scanner class?? or any
other classes? i know that we can get a string and then put it in a
StringBuilder like this:
import java.util.Scanner;
public class Sade {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String str ;
str = scan.nextLine() ;
StringBuilder strb = new StringBuilder(str);
}
}
or through using append(). but is there anyway to get StringBuilder
directly from user??
