How to add byte[] to Vector/ArryList

Question

Hi
my intention is like add the byte[] to Vector/ArryList .. and each element in byte array will be appper as vector elements.
i mean Each byte[i] element will be as i th element in vector/ArryList
byte [] b=myString.getBytes();
Vector v=new Vector();
v.add(b); // add each element of byte array to vector.....
Wat i have to do?
plz give me solution

Answer 1

And see it my first code
import java.io.*;
import java.util.Scanner;
//import herong.CipherDES;
class Test
     private byte[] theKey;
     private byte[] theMsg;
        private StringBuffer DecMesg;
     private StringBuffer PlainMesg;     
     private StringBuffer s1;     
     private StringBuffer s2;
     public Test()
               theKey = null;
                  theMsg = null;
     public void initialize(String str1,String str2)
               s1=new StringBuffer(str1);
               s2=new StringBuffer(str2);
               while((s1.length()%8)!=0)
                         s1.append(" ");
               if(s1.length()<s2.length())
                         while(s2.length()%8!=0)
                                   s2.append(" ");     
               else
                         while(s2.length()<s1.length())
                                   if(s2.length()%s1.length()<8)
                                        s2.append(str2);
                                   else
                                        s2.append(" ");                              
     public String encryptDES(String str1,String str2)
               DecMesg=new StringBuffer();
               try
               initialize(str1,str2);
               for(int i=0;i<s1.length();i=i+8)
                         String Mesg=s1.substring(i,i+8);
                         String Key=s2.substring(i,i+8);
                         theMsg = Mesg.getBytes();
                         theKey = Key.getBytes();
                             byte[][] subKeys = CipherDES.getSubkeys(theKey);
                         byte[] theCph = CipherDES.cipher(theMsg,subKeys,"encrypt");//cipherDESis a method in my class
                          String Cipher = new String(theCph);                    
                         DecMesg=DecMesg.append(Cipher);
               catch(Exception e)
               e.printStackTrace();
          return DecMesg.toString();
     public String decryptDES(String str1,String str2)
               PlainMesg=new StringBuffer();
               initialize(str1,str2);
               try
               for(int i=0;i<s1.length();i=i+8)
                         String Mesg=s1.substring(i,i+8);
                         String Key=s2.substring(i,i+8);
                         theMsg = Mesg.getBytes();
                         theKey = Key.getBytes();
                             byte[][] subKeys = CipherDES.getSubkeys(theKey);
                         byte[] thePlain = CipherDES.cipher(theMsg,subKeys,"decrypt");
                          String Plain = new String(thePlain);
                         PlainMesg=PlainMesg.append(Plain);
               catch(Exception e)
               e.printStackTrace();
          return PlainMesg.toString();
class kk
      public static void main(String[] a)
                Test obj=new Test();     
          String s1="chinturao";          
          String s2="bavaanil";
          String s3="Hello  to all from krish and from idnia how r u i am fine";
          String encMesg=obj.encryptDES(s3,s1);          
          String decMesg=obj.decryptDES(encMesg,s1);
          System.out.println(decMesg);
}wheni execute it it gives worng out put like below
Hello  to all from krish and fro.}§&#9794;I&#9794;¶&#8805;how r u i am fineso i think its the problem with srings when Mesg are ciphers so i wish to make use if bytes.
