How to print out a hashset
25,389
You have to print the content of your array. Arrays.toString(char[] a)
will do that for you :
System.out.println(" Iterating over HashSet in Java current object: " + Arrays.toString(itr.next()));

I just now started working with hashsets and I am trying to print it out but all it prints out is its location i tried Iterator and .toString() here is my code :
char [] a = RandomWord.toCharArray(); HashSet<char[]> set = new HashSet<char[]>(); set.add(a); Iterator<char[]> itr = set.iterator(); while(itr.hasNext()){ System.out.println(" Iterating over HashSet in Java current object: " + itr.next().toString()); } }
