You can't do that. Integer objects are immutable. The best Java can do
is create a new instance using the modifed value. For example:

// C++
void modify(int& data)
{
   ++data;
}
// ...
int main()
{
  int value = 1;
  modify(value);
}

// Java
Integer modify(Integer data)
{
  return new Integer(++data.intValue());
}
// ....
   Integer answer = modify(new Integer(1));
