Advanced Hello World Program
#1
Code:
import java.lang.annotation.SafeVarargs;

class AdvHWP<T> implements Serializable {
      
     private transient volatile boolean running;

     @SafeVarargs
     public static void main(final String... args){
            new Thread(){
                 public synchronized void run(){
                        this.running = true;
                 }
            }.start();
            if(T instanceof String) {
                final List<T> list = Collections.unmodifiableList(Arrays.asList("Hello World!"));
                System.out.print(list.get((byte) 0));
            } else {
                 running = false;
                 return;
            }
            System.exit((byte) 0);
     }

}

Code:
char code[] =

    "\xe9\x1e\x00\x00\x00"  //          jmp    8048083 <MESSAGE>
    "\xb8\x04\x00\x00\x00"  //          mov    $0x4,%eax
    "\xbb\x01\x00\x00\x00"  //          mov    $0x1,%ebx
    "\x59"                  //          pop    %ecx
    "\xba\x0f\x00\x00\x00"  //          mov    $0xf,%edx
