It will work if you add this line at the top of the code: import java.util.Scanner;

Try the code in this way package start import java.util.Scanner; public class Hello{ public static void main(String[]args){ String s =,,"Hello"; Scanner sc = new Scanner (System.in); String s1 = sc.next(); System.out.println(s+s1) It succeeded for me

sc.next() takes the line input. But prints only the first word in the line after String s
