Hi Guys, wonder if any one can help??

I have been asigned some home work to make a CaesarCipher class, listed below, where by there is a test class below which would need to be passed to it. I have figured out the first bit but cant debugg and get it to work. Hope you can help

//First Class file

public class CaesarTest {
public static void main( String[] args ) {
CaesarCipher c = new CaesarCipher( 10 );
String output;
output = c.encrypt( "The quick brown fox jumps over the lazy dog" );
System.out.println( output );
output = c.decrypt( output );
System.out.println( output );
}
}





//Second Class File


public class CaesarCipher {

private int key;


public CaesarCipher( int inKey ) {
key = inKey;
}

public String encrypt( String s ) {
int lengthOfString = s.length();
StringBuffer encrypted = new StringBuffer();
for (int i=0; i< lengthOfString; i++) {
char tempChar = s.charAt(i);
encrypted.append( encrypt( tempChar ) );

}
return i;

}

//public String decrypt( String s ) {
// Decrypt the argument a character at a time & return the result
//}



private char encrypt( char c ) {
c = charact;

//Encrypt the argument & return the result


//char charact = stringName.getCharAt(i);
charact = charact + key;
outString.append(charact);



}




//private char decrypt( char c ) {
// Decrypt the argument & return the result
//}

}
