Arrays Problem (Advanced Java...Need Help)

[Zebra]

I am suppose to make an array with a social secruity numbers for each state (fake ones). When the user inputs their SSN then it then returns what state they are from.

For example: if Jim enters
132-11-0987, then the program would respond, "Hello Jim, you we born in
New York State."

Here are the numbers for each state:

001-003 NH 400-407 KY 530 NV
004-007 ME 408-415 TN 531-539 WA
008-009 VT 416-424 AL 540-544 OR
010-034 MA 425-428 MS 545-573 CA
035-039 RI 429-432 AR 574 AK
040-049 CT 433-439 LA 575-576 HI
050-134 NY 440-448 OK 577-579 DC
135-158 NJ 449-467 TX 580 VI Virgin Islands
159-211 PA 468-477 MN 581-584 PR Puerto Rico
212-220 MD 478-485 IA 585 NM
221-222 DE 486-500 MO 586 PI Pacific Islands*
223-231 VA 501-502 ND 587-588 MS
232-236 WV 503-504 SD 589-595 FL
237-246 NC 505-508 NE 596-599 PR Puerto Rico
247-251 SC 509-515 KS 600-601 AZ
252-260 GA 516-517 MT 602-626 CA
261-267 FL 518-519 ID 627-645 TX
268-302 OH 520 WY 646-647 UT
303-317 IN 521-524 CO 648-649 NM
318-361 IL 525 NM *Guam, American Samoa,
362-386 MI 526-527 AZ Philippine Islands,
387-399 WI 528-529 UT Northern Mariana Islands

And what is your question?

What have you done so far?

[Zebra]

I changed the question around to be understanded. (friendly bump)

Hey Zebra.

Here is a code example for you. This does exactly what you want.. You will need to finish it off though with the rest of the States. Just carry on with the 'else if' statements.

Code:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class SSN {

   public static void main(String[] args) {
		
      String sSN = null;
      String name = null;
      String state = null;

	System.out.println("What is your name?");
	BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); 

     try
     { 
        name = br.readLine(); 
     }
     catch (IOException ioe) 
     { 
         System.out.println("Error reading name");
         System.out.println(" ");
         System.exit(0); 
      } 
	      
      System.out.println("What is your Social Security Number?");
      BufferedReader br2 = new BufferedReader(new InputStreamReader(System.in)); 

      try
      { 
         sSN = br.readLine(); 
      }
      catch (IOException ioe) 
      { 
         System.out.println("Error reading Social Security Number!");
         System.out.println(" ");
         System.exit(0); 
      } 
		   
			
if(sSN.contains("001-003")){
      state = "NH";
      System.out.println("Hello " + name + ". You were born in " + state);	
}
else if(sSN.contains("400-407")){
      state = "KY";
      System.out.println("Hello " + name + ". You were born in " + state);	
}
else if(sSN.contains("004-007")){
      state = "ME";
      System.out.println("Hello " + name + ". You were born in " + state);	
}
else if(sSN.contains("408-415")){ 
      state = "TN";
      System.out.println("Hello " + name + ". You were born in " + state);	
}
else if(sSN.contains("531-539")){
      state = "WA";
      System.out.println("Hello " + name + ". You were born in " + state);	
}
//etc
		
		
		
else
{
System.out.println("Your Social Security Number: " + sSN + " Does not match any State!");
}
		
   }

}

Or we can cut the ugliness of checking for each state with an if

Code:

import java.io.*;
import java.util.*;

public class SSN
{
    public static void main(String[] args) throws IOException
    {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Enter name: ");
        String name = br.readLine();

        String ssn = null;
        String ssnTk1 = null;
        String ssnTk2 = null;
        while (true)
        {
            System.out.print("Enter SSN: ");
            ssn = br.readLine();

            StringTokenizer st = new StringTokenizer(ssn, "-");
            int tkNum = st.countTokens();
            if (tkNum < 2)
            {
                System.out.println("Invalid SSN: " + ssn + " Try again!");
            }
            else
            {
                ssnTk1 = st.nextToken();
                ssnTk2 = ssnTk1 + "-" + st.nextToken();
                break;
            }
        }

        String state = ssnToState.get(ssnTk2);
        if (state == null)
        {
            state = ssnToState.get(ssnTk1);
        }

        if (state != null)
        {
            System.out.println("Hello " + name + ". You were born in " + state);
        }
        else
        {
            System.out.println("Your Social Security Number: " + ssn + " Does not match any State!");
        }
    }

Yeah nice work danielstoner.

That is indeed another way to do it, but Zerba is new to Java and I would of thought the 'if then' statements are much easier to understand!

[Zebra]

I am using that code that daniel gave me and I can't get it to say i am from a state yet. Here is my output.

[DonCash]

Looking at the list in daniels code, 200-51-300 isnt in there. Thats why its not matching.

[danielstoner]

Things don't happen by magic in code You didn't provide a 200-anything entry in your original post. Find the mappings from SSN to state, fill the initialization static block and then you can find everything. Good luck

[Zosden]

You could use the power of dark magic.

Just import java.DarkMagic

And everything will work.lol it was to good to pass
