Weird Funny Java!
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 ;)
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.
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
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
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. ;)
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
