Question

I'm also having trouble on dividing the code into methods. This is my work done so far and net beans give me a lot of errors. Help!

package caesarcipher;
import textio.TextIO;

/**
*
* @author
*/
public class CaesarCipher {

enum code {encodeText, decodeText };
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
  
String code;
char x;
  
int totalcount = 0;
  
while(true){
TextIO.put("Type in an E to encode a message or a D to decode a message "
+ "or an X to exit the program: ");
code = TextIO.getlnWord();
  
switch(code.toUpperCase()){
case "E":
TextIO.putln("You have chosen to encode a message!");
break;

case "D":
TextIO.putln("You have chosen to decode a message!");
break;
  
case "X":
TextIO.putln("Bye!");
return;
  
  
}
}   
  
}
  
  
static String encodeText(String code){
switch(code){

TextIO.put("Enter a shift count: ");
int shift = TextIO.getlnInt();

TextIO.put("Enter your plain text: ");

char[] message = TextIO.getln().toUpperCase().toCharArray();
for(int i=0; i < message.length; i++){

char alpha;
if((message[i] >= 'A' && message[i] <= 'Z')){
int cryp =((int)message[i] + (shift));
if(cryp > (int) 'Z'){
cryp -= 26;
}
alpha = ((char)cryp);
}
else {
alpha = message[i];
}
System.out.print(alpha);
}
System.out.print("\n");
break;
}
}
static String decodeText()
switch(code){

TextIO.put("Enter a shift count: ");
shift = TextIO.getlnInt();
  
TextIO.put("Enter the encrypted message: ");
char[] dcode = TextIO.getln().toUpperCase().toCharArray();
for(int i=0; i< dcode.length;i++){
  
char alpha;
if((dcode[i] >= 'A' && dcode[i] <= 'Z')){
int cryp =((int)dcode[i]) - shift;
if(cryp < (int)'A'){
cryp += 26;
}
alpha = ((char)cryp);
  
} else {
alpha = dcode[i];
  
}
System.out.print(alpha);
}
System.out.print("\n");
break;
}

==================================
You need to call these functions now, I have just made it compile....You need call those functions generate Output

1357 1358 1359 1360 1361 enum code { encodeText, decodeText Textio Console Type in an E to encode a message or a D to decode a message or an X to exit the }; 1362 /** * @param args the command line arguments */ public static void main(String[] args) { 1363 1364 1365 1366 1367 1368 1369 1370 1371 1372 1373 1374 String code; char x; int totalcount = 0; 1375 while (true) { Textio.put( "Type in an E to encode a message or a D to decode a message " + "or an X to exit the proqram: ");

PLEASE COMMENT if there is any concern.
