Having problems on queue! HELP ME!

[AnnaPatricia]

I just want to convert my program to QUEUE
this whole thing but i cant find any program in the net that would help me do it

Can anyone help me do this stuff or just post your samples regarding on it

im creating a Caesar Cipher Code ^_^


import java,util.*;
public class SecretCodeDemo {
public static void main(String[] args) {
Scanner kbd=new Scanner (System.in);
int choice = kbd.nextInt();
String monthString;
switch (month) {
case 1:
encrypt();
break;
case 2:
decrypt();
break;
case 3:
System.out.println("Good bye!!");
System.exit(0);
break;

default:
System.out.println("Invalid Output.");
break;
}

public class encrypt(){
try{
String message;
System.out.println("Input: ");
Scanner kbd=nextLine();
int shiftKey = Integer.parseInt(args[1]);
shiftKey = shiftKey % 26;

String cipherText = "";

for (int i=0; i<plaintext.length(); i++){
int asciiValue = (int) plaintext.charAt(i);
if (asciiValue < 65 || asciiValue > 90){
cipherText += plaintext.charAt(i);
continue;
}

int basicValue = asciiValue - 65;
int newAsciiValue = 65 + ((basicValue + shiftKey) % 26) ;
cipherText += (char) newAsciiValue;

}
System.out.print(cipherText);
}
catch(Exception e){e.printStackTrace();}
}
}
}
}




POSSIBLE OUTCOME:

Message: Data
Key value ( for each letter ): 2 1 5 4 (for each letter )
Outcome: Fbze

Help me out ^_^
THANKS A LOT!

This is my encrypt code
public class encrypt(){
try{
System.out.println("Message: ");
String ciphertext = kbd.nextLine();
int shiftKey = Integer.parseInt(args[1]);
shiftKey = shiftKey % 26;

String plainText = "";

for (int i=0; i<ciphertext.length(); i++){
int asciiValue = (int) ciphertext.charAt(i);
if (asciiValue < 65 || asciiValue > 90){
plainText += ciphertext.charAt(i);
continue;
}

int basicValue = asciiValue - 65;

int newAsciiValue = -1000;

if (basicValue - shiftKey < 0){

newAsciiValue = 90 - (shiftKey - basicValue) + 1;
}
else{
newAsciiValue = 65 + (basicValue - shiftKey);
}
plainText += (char) newAsciiValue;

}
System.out.print(plainText);
}
catch(Exception e){e.printStackTrace();}
}
}

I just want to convert my program to QUEUE

I don't understand your statement above. Can you clarify what it is exactly that you're trying to do, and in particular what a queue has to do with it.

this whole thing but i cant find any program in the net that would help me do it

You're likely much better not "finding" any program, but rather writing your own program.

Can anyone help me do this stuff or just post your samples regarding on it

I can't speak for others, but until you clarify your problem, there's little help I have to offer. Most of us do best answering direct straight-forward questions.

This most here will understand and know how to do.

import java,util.*;
public class SecretCodeDemo {
    public static void main(String[] args) {
	Scanner kbd=new Scanner (System.in);
        int choice = kbd.nextInt(); 
        String monthString;
        switch (month) {
	    case 1:
		encrypt();
		break;
	    case 2:
		decrypt();
		break;
	    case 3:
		System.out.println("Good bye!!");
		System.exit(0);
		break;
            
            default: 
		System.out.println("Invalid Output.");
                     break;
        }
        
	public class encrypt(){
try{ 
	String message;
	System.out.println("Input: ");
	Scanner kbd=nextLine();
    	int shiftKey = Integer.parseInt(args[1]); 
      	shiftKey = shiftKey % 26;  
       
    	String cipherText = ""; 
  
      for (int i=0; i<plaintext.length(); i++){ 
         int asciiValue = (int) plaintext.charAt(i); 
         if (asciiValue < 65 || asciiValue > 90){ 
            cipherText += plaintext.charAt(i); 
            continue; 
         } 
          
         int basicValue = asciiValue - 65; 
         int newAsciiValue = 65 + ((basicValue + shiftKey) % 26)  ; 
         cipherText += (char) newAsciiValue; 
  
       } 
       System.out.print(cipherText);              
      } 
     catch(Exception e){e.printStackTrace();} 
  } 
}
    }
}

I've added [code] [/code] tags to your code above to make it easier to read. You may wish to edit your original post and add these yourself so that others will be able to read and understand your posted code.

Please don't PM people for solutions.
We won't get to the threads any faster.

uhm i mean i need to use a circular array queue on the encrypt and decrypt method i need to use.


Do you think i can use this program?
How?

teach me please willing to learn

public interface QueueADT<T>
{
/**
* Adds one element to the rear of this queue.
*
* @param element the element to be added to the rear of this queue
*/
public void enqueue (T element);
/**
* Removes and returns the element at the front of this queue.
*
* @return the element at the front of this queue
*/
public T dequeue();
/**
* Returns without removing the element at the front of this queue.
*
* @return the first element in this queue
*/
public T first();
/**
* Returns true if this queue contains no elements.
*
* @return true if this queue is empty
*/
public boolean isEmpty();
/**
* Returns the number of elements in this queue.
*
* @return the integer representation of the size of this queue
*/
public int size();
/**
* Returns a string representation of this queue.
*
* @return the string representation of this queue
*/
public String toString();
}
