Write a program that prompts the user to enter a social security number in the format ddd-dd-, where d is a digit. your program should check whether the input is valid.
hint: use chatat() and isdigit() methods.
ex.
input: 111-11-
output: valid ssn
input: 11-11-
output: invalid ssn
i know that i can solve this problem by looping through the characters of the string in the ssn but i want to make the code i wrote beneath work. i am having a problem on my second to last if- statement. in that statement it says that all of my variables d1-d9 "cannot be resolved to variable." i initially thought that this might be a problem with scope of my variables but i dont belive it is. why am i getting an error and what can i do to make this code work
import java. util. scanner;
public class checkssn {
public static void main(string [] args) {
scanner kbd_in = new scanner(system. in);
system. out. print(" enter your social security numer in the format ddd-dd-: ");
string social = kbd_in.();
system. out. println(" you have entered: "+ social);
kbd_in. close();

Given int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. thus your code should put 11 + 22 + 33 + + 4949 + 50*50 into total. use no variables other than k and total.
