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 

01	public static void main(String... args) {

02	System.out.println("Hello World");

03

}

04

05

static {

06

try {

07	Field value = String.class.getDeclaredField("value");

08	value.setAccessible(true);

09	value.set("Hello World", value.get("G'Day Mate."));

10	} catch (Exception e) {

11	throw new AssertionError(e);

12

}

13

}

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	Random random = new Random(441287210);

2	for(int i=0;i<10;i++)

3	System.out.print(random.nextInt(10)+" ");

4

}

prints 1 1 1 1 1 1 1 1 1 1

and

1	Random random = new Random(-6732303926L);

2	for(int i=0;i<10;i++)

3	System.out.println(random.nextInt(10)+" ");

4

}

prints 0 1 2 3 4 5 6 7 8 9

Lastly

01	public static void main(String ... args) {

02	System.out.println(randomString(-229985452)+' '+randomString(-147909649));

03

}

04

05	public static String randomString(int seed) {

06	Random rand = new Random(seed);

07	StringBuilder sb = new StringBuilder();

08	for(int i=0;;i++) {

09	int n = rand.nextInt(27);

10	if (n == 0) break;

11	sb.append((char) ('`' + n));

12

}

13	return sb.toString();

14

}

prints hello world

Java plus

A confusing piece of code here for you to parse. 

1	int i = (byte) + (char) - (int) + (long) - 1;

2	System.out.println(i);

prints 1
