Sometimes we can do really weird and funny things with Java; Some other times we are just being creative!
Take a look at the following three examples and you will find out what I mean!
Have Fun!
Strine translator
Translating to Strine ;)
01 02 03 04 05 06 07 08 09 10 11 12 13 | public static void main(String... args) { System.out.println("Hello World"); } static { try { Field value = String.class.getDeclaredField("value"); value.setAccessible(true); value.set("Hello World", value.get("G'Day Mate.")); } catch (Exception e) { throw new AssertionError(e); } } |
prints
G’Day Mate.
BTW: Strine is the Australian Dialect of English.
Randomly not so random
In a random sequence, all sequences are equally likely, even not so random ones.
1 2 3 4 | Random random = new Random(441287210); for(int i=0;i<10;i++) System.out.print(random.nextInt(10)+" "); } |
prints 1 1 1 1 1 1 1 1 1 1
and
1 2 3 4 | Random random = new Random(-6732303926L); for(int i=0;i<10;i++) System.out.println(random.nextInt(10)+" "); } |
prints 0 1 2 3 4 5 6 7 8 9
Lastly
01 02 03 04 05 06 07 08 09 10 11 12 13 14 | public static void main(String ... args) { System.out.println(randomString(-229985452)+' '+randomString(-147909649));}public static String randomString(int seed) { Random rand = new Random(seed); StringBuilder sb = new StringBuilder(); for(int i=0;;i++) { int n = rand.nextInt(27); if (n == 0) break; sb.append((char) ('`' + n)); } return sb.toString();} |
prints hello world
Java plus
A confusing piece of code here for you to parse. ;)
1 2 | int i = (byte) + (char) - (int) + (long) - 1;System.out.println(i); |
prints 1

For the confusing piece of code, (long) puts a curse on the next character. It does it if you put “;” for the rest of the expression, too. Putting “+ 0” after (long) removes the curse. I don’t know why. Magic isn’t big on explanation.
Out of curiosity, did you brute-force to find the seed that’d produce “Hello, World”? Or is there an easier way to do that?
haha biggest noob programmer i ever seen
this is confusing, I don’t tske any iterest in programming, but I find it interesting
