Sets

[kevin Noronha]

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??

[HeavenAgain]

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

code:

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

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);
