Explanation / Answer

Hi

I have fixed the issue and highlighted the code changes below.

Lab3d.java

import java.util.Scanner;

public class Lab3d {

  
   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       String phoneNum = "";
      
       System.out.println("Enter 10-digit telephone number: ");
       phoneNum = scan.next();
       System.out.println("You entered "+phoneNum);
       if(phoneNum.length() != 10){
           System.out.println("Please enter a 10-digit number.");
       }
       else{
           String areaCode = phoneNum.substring(0,3);
           String exchangeCode = phoneNum.substring(3,6);
           String number = phoneNum.substring(6,10);
           System.out.println("The area code is "+areaCode);
           System.out.println("The exchange is "+exchangeCode);
           System.out.println("The number is "+number);
           System.out.println("The complete telephone number is ("+areaCode+") "+exchangeCode+"-"+number);
       }
      
      
      
   }

}

Output:

Enter 10-digit telephone number:
1234567890
You entered 1234567890
The area code is 123
The exchange is 456
The number is 7890
The complete telephone number is (123) 456-7890

Enter 10-digit telephone number:
111222333444
You entered 111222333444
Please enter a 10-digit number.
