Sets

-----------------------------------

what code would you use to print out contents from a set
Example:
HashSet set=new HashSet();
set.add(5);


How can you print out the value 5??

RE:Sets

-----------------------------------

depends on how you want to work this, there is a contains method, which you can check if 5 is in there, so we do if (set.contains(5))
    System.out.println(5);
//or use the toString method
System.out.println(set);
//or converting it to array, and treat it like an array
set.toArray();any more? I'm not sure... if there is a better answer, let me know :)

Re: Sets

-----------------------------------

With a HashSet you can can test if 5 is in your set e.g.
set.contains(5)

You can also print everything like:
for(Integer i : set)
System.out.println(i);
