I disagree, here is some wonderful code obfuscation. Were I more 
involved, I would have tried to find a better obfuscation than roman 
numerals for the main string, but, with any luck, the OP is reading this 
in a client with variable-width font and the text runs together as a 
whole lot of I's.
public class Test {
   public static void main(String... args) {
     char[] K = new char[256];
     int K = 0, Κ = 0;
     char[] К = ("ⅠⅠⅠⅠⅠⅠⅠⅠⅢⅢⅢⅢⅢⅢⅤⅣⅠⅢⅢⅢⅢⅢⅢⅢⅢⅡⅥⅠⅠⅢⅢⅢⅢⅢⅢⅢⅢⅢⅢⅡⅡⅡⅢⅤⅣⅠ" +
       "ⅢⅠⅢⅡⅡⅥⅠⅠⅦⅡⅤⅠⅦⅣⅡⅣⅥⅠⅠⅦⅡⅡⅡⅢⅢⅤⅣⅠⅢⅠⅢⅡⅡⅥⅠⅠⅦⅡⅤⅠⅦⅣⅡⅣⅥⅠⅠⅦⅡⅡⅡⅢⅢⅢⅤⅣⅠⅢⅠⅢⅡⅡ" +

"ⅡⅡⅥⅠⅠⅦⅡⅤⅠⅦⅣⅡⅣⅥⅠⅠⅦⅡⅡⅡⅢⅢⅢⅢⅢⅢⅢⅢⅤⅣⅠⅢⅠⅢⅡⅡⅥⅠⅠⅦⅡⅤⅠⅦⅣⅡⅣⅥⅠⅠⅦⅡⅡⅡ").toCharArray();

     int Ⲕ = К.length;
     while (Κ < К.length) {
       switch (К[Κ]) {
       case 'Ⅰ': K++; break;
       case 'Ⅱ': K--; break;

       case 'Ⅶ': System.out.print(K[K]); break;
       }
       Κ++;
     }
   }

   private static int Ｋ(char[] К, int Κ) {
     int K = 0;
     for (++Κ; Κ < К.length; Κ++) {
       if (К[Κ] == 'Ⅴ') K++;
