Help Needed Regarding java.security.NoSuchAlgorithmException

Respected members,

I have a program -

Code:

---

import java.io.*;
import java.security.*;

public class TestSerial {
       
        public static void main(String args[])
        {
                String serialNumberEncoded ;

      String calculateSecurityHash(String stringInput, String algorithmName )
        throws java.security.NoSuchAlgorithmException                {
             
             
               
                String hexMessageEncode = "";
            byte[] buffer = stringInput.getBytes();
            java.security.MessageDigest messageDigest = java.security.MessageDigest.getInstance(algorithmName);
            messageDigest.update(buffer);
            byte[] messageDigestBytes = messageDigest.digest();
           
            for (int index=0; index < messageDigestBytes.length ; index ++)
            {
                int countEncode = messageDigestBytes[index] & 0xff;
                if (Integer.toHexString(countEncode).length() == 1) hexMessageEncode = hexMessageEncode + "0";
                hexMessageEncode = hexMessageEncode + Integer.toHexString(countEncode);
            }
            return hexMessageEncode;
          }
           
            serialNumberEncoded = calculateSecurityHash(fullNameString,"MD2") +  calculateSecurityHash(fullNameString,"MD5") +
                calculateSecurityHash(fullNameString,"SHA1");

            System.out.println("Serial MATCH");
        else
            System.out.println("Serial MIS-MATCH");
               
        }

       
       
}

The Program Will generate The Following Error, And I can't Figure Out Why The Problem Will Generate -

Code:

---

Multiple markers at this line
        - Syntax error on token ",", ; expected
        - Syntax error on token "(", ; expected
        - Syntax error, insert ";" to complete
        LocalVariableDeclarationStatement

---

Did I missed to add any header file ? or There is some Syntax error. Please suggest.

Best Regards
David

Count your curly brackets, they have to match; as it is now you're trying to define another method in the body of your main method body. You can't do that in Java.

kind regards,

Jos

Dear Jos,

Code:

---

---

Can i Move The method out side of the static main function ? Please Suggest.

You have to do that because as your code is now it doesn't compile; the structure of your class should be like this (pay attention to the curly brackets):

Code:

---

public class TestSerial {
       
  public static void main(String args[]) { ... }

  String calculateSecurityHash(String stringInput, String algorithmName )
        throws java.security.NoSuchAlgorithmException { ... }
}

kind regards,

Jos

Dear Jos,

I Have Tried your Solution, Still It Gives Error. I am Attaching The File. Kindly Examine the File. Please Check And Please Please Let Me Know The Issue.

I am Looking Forward To Your Reply.

Your main method doesn't do anything, it just defines two local String variables and terminates. What were the issues you experienced?

Sorry. I just want to call the function into my main function. so that, the main function will call the sub-function and run the program.

Basically I want to call calculateSecurityHash() method inside the public static void main.


The Output may look like the this. (Please Check The Attachment).

Well, call the method from your main( ... ) method; note that the other method isn't static so you need to have an object to call that method on; I don't know if you want that (you can also make the other method static so no objects are needed).

kind regards,

Jos
