sapresti tradurre in java questo codice?
Vorrei fare delle prove.
Grazie



#include <stdio.h>
#include <stdlib.h>

void print_double_bytes(double d) {
   unsigned char *p = (unsigned char*)&d;
   for (size_t i=0; i<sizeof d; i++) {
     printf("%.2x", p[i]);
   }
   printf("\n");
}

int main() {
     double a = 1.1;
     double b = 2.2;
     double c = 3.3;

     print_double_bytes(a);
     print_double_bytes(b);
     print_double_bytes(a+b);
     print_double_bytes(c);

     return 0;
}
