Language- Java

I was trying to do this, but I somehow was not able to get the correct output. I have posted what I have done below. Please Help!

------------------------------------------------------------------------------------------------

public static void main(String[] args) { Scanner input= new Scanner(System.in); System.out.print("Enter a Social Security Number in the format 111-11-1111: "); String n1 =input.nextLine();

if(n1.length()==11){ if(Character.isDigit(n1.charAt(0)) && Character.isDigit(n1.charAt(1)) && Character.isDigit(n1.charAt(2)) && Character.isDigit(n1.charAt(3)) && Character.isDigit(n1.charAt(4)) && Character.isDigit(n1.charAt(5)) && Character.isDigit(n1.charAt(6)) && Character.isDigit(n1.charAt(7)) && Character.isDigit(n1.charAt(9)) && Character.isDigit(n1.charAt(9)) && Character.isDigit(n1.charAt(10)) && (n1.charAt(3)== '-') && (n1.charAt(6)== '-')){ System.out.print( n1 + "is an valid s1ocial security number."); } else { System.out.print( n1 + "is an invalid social security number."); } }else{ System.out.print( n1 + "is an invalid social security number."); }
